In the Luoyang Basin during the Han, Wei, Sui, and Tang dynasties, the flow patterns of the Yi, Luo, Chan, and Jian rivers were closely related to their geological setting. The orientations of these rivers are predominantly determined by the underlying geological fault lines of the basin. The orientations of the Yi and Luo rivers are mainly determined by east-west and northeast-oriented fault lines, with the flow path of the Luo River primarily influenced by the Matun-Yanshi fault and the Yi River influenced by the Yiyang-Yanshi fault. Jian and Chan Rivers share simultaneous spatial similarities and transient transformation similarities, both following city site migrations, turning from being sectioned eastward during Han and Wei dynasties to falling back to the natural southward flow during Sui and Tang dynasties. Luo River exhibited a trend of continual northward transformation during Han, Wei, Sui, and Tang dynasties, while Yi River constantly extends eastward and southward. Over historical periods, the Yi and Luo rivers gradually separated north and south, with their confluence point shifting eastward. Unequal north-south subsidence and a northward tilt of the sedimentary center caused Luo River to migrate northward, while a central bulge and ‘two cut first base’complex fault depression caused Yi River to extend eastward and southward.

The Tang Dynasty Chinese cliff carvings discovered in the Dil mountain of Ulziit in the central Gobi Province of Mongolia indicate that this area was an important node on the grassland transportation line at that time. The route through the desert to capital of the Uyghur Empire, as recorded in the New Book of Tang passed through this area as the ‘Eastern Uyghur Road’, also known as the ‘the road of having an audience with Tengri Khan’. The inscriptions were carved during the rule of restraint period of the Tang Dynasty in the second year of Linde, which confirmed the historical event that Emperor Gaozong of the Tang Dynasty offered sacrifices to heaven and earth in Mount Tai and invited the leaders of Tiele tribes in the Boreal desert to come, which reflected the communications between the Tang Dynasty and the northern nomads and the control of the Tang government over the vassal prefectures in the Boreal desert.

During the period of the Qing Dynasty and the Republic of China, Suiyuan, which was located in the western part of the Northern Agricultural Pastoral Ecotone, underwent diversified changes in its industrial structure in response to changes in the situation at home and abroad. Diversification became a prominent feature of local economic geography. By the 1930s, it was mainly reflected in the non-local primary industries of agriculture, industry, commerce and transportation, which infiltrated, superimposed and transformed with the local native nomadic economy into a modernity and diversified regional economic system. Before that, it could only be called piecemeal changes, rather than full scale changes. Thereafter, Suiyuan had evolved from a nomadic landscape of cattle and sheep throughout the territory in the early Qing Dynasty, to a new pattern of diversified industries in the late Republic of China, which was characterized by pastoral farming, numerous industrial enterprises, prosperous domestic and foreign trade, and interlaced roads and railways. It had become a common home for Mongolian and Han peoples with a prosperous regional economic and harmonious inter-ethnicity relations.

During the confrontation between the Northern Song and the Liao dynasties, the song army attached great importance to the northern border defense system of Hedong Lu. The defense line runs for more than 400 miles, along which a defense system with Daizhou as the center, and Fanshi and Guxian as the East and West wing respectively, has been formed. It mainly consists of citadels and fortresses and the aim is to deter the southward attacks through the Xiagu road of the Liao army. The fortresses are surrounded by defensive facilities such as square fields, protective forests, stone walls, ditches, and beacon towers. Taken together, they form a defense system integrating the functions of monitoring, reconnaissance, counter-attacking, military information transmission and so on. Horizontally, the distances between fortresses in different regions ranged from eight to seventy miles, with the majority at around thirty. Vertically, they rely on hinterland counties and towns, thus forming a three-tier defense system, which played a key role in the border defense system of the Northern Song Dynasty.

The tiers of prefectures and counties are important indicators that reflect their political status, population and economic importance. By using historical quantitative analysis and GIS analysis methods, this paper unpacks the spatiotemporal changes of 339 prefectures and 1 607 counties in Tang Dynasty. The results show that: (1) The number of prefecture tier Fu (府), Fu (辅), Xiong (雄) and county tier Chi (赤), Ji (畿), Ci-Chi (次赤) and Ci-Ji (次畿) was relatively stable in Tang Dynasty, while the number of Shang (上), Zhong (中), Xia (下) prefectures and counties changed drastically. In the late Tang Dynasty, the number of upgraded prefectures and counties was more than that of degraded prefectures and counties, with the most significant hierarchical change took place from Kaiyuan (713-741) to Yuanhe (806-820). (2) The spatio-temporal changes of prefectures and counties in Tang Dynasty was “high in the north and low in the south”. Guanzhong Plain was the highest area in the prefecture and county level. The temporal change was “falling in the north and rising in the south”. The Plain of Hubei and Hunan, Poyang Lake Plain and Taihu Plain in the middle and lower reaches of the Yangtze River rose most significantly. (3) The tiers of prefectures and counties in the vicinity of the capital of the Tang Dynasty were most affected by political factors, while the tiers of the frontier fortresses and traffic throats were most affected by military factors. Other prefectures’ and counties’ tiers were mainly affected by economic factors, especially population size. (4) The spatio-temporal changes of the tiers of prefectures and counties in Tang Dynasty reflected the eastward and southward movement of the national political, demographic, urban and economic centers after the An-Shi Rebellion in the middle of the Tang Dynasty.

This paper compiles panel data on prefectural land and labor tax for the years 1717, 1748, 1784, and 1820 based on historical data, and uses geographic information system to analyze its spatially divergent patterns. The spatial panel model is used to explore the role of topographic factors on these characteristics. The results show that: (1) The distribution of land and labor tax is significantly limited by altitude, and the high tax distribution is all located below 600 meters above the sea level. (2) There was a significant positive spatial correlation of land and labor tax. The local Moran index showed an uneven development pattern. High-high clustering mainly in eastern China and low-low clustering mostly in western and southwestern China. The gravity model shows that the formation of a spatially positive autocorrelation pattern of taxes is most influenced by the agglomeration effect of the Yangtze River Delta region, as well as some northern provinces. (3) Spatial panel regression results show that population is positively correlated with land and labor tax, and altitude and slope are negatively correlated with it. (4) The influence of topographic factors on tax amount distribution gradually decreased, while the influence of governance factors gradually increased.

The Lixia River Plain, consisting of a great number of small lakes and swamps, spread widely in the north of Jiangsu Province in history. After 1570, the flood of Huaihe River entering Lixia River Plain continued to increase, which caused great changes in the distribution of lakes and drainage pattern in the region. After 1596, the flood from the Jinghe River and the Ziyinggou River entered into the Guangyang Lake, and then flowed through the Sheyang Lake into the sea. The waters in the southeast of Gaoyou all converge in the Luyang Lake. After 1681, due to the southward shift of the Guihai Dams, floods converged in the middle of the Lixia River Plain and overflowed from the south to the north. As a result, the Dazong Lake and other lakes were connected and merged as a whole. Due to the decrease of flood, the Guangyang Lake was divided into several scattered lakes. Whether the Guihai Dams were opened or not, it would directly affect the hydrological environment of the Lixia River Plain, and thus form two completely different lake distribution and drainage patterns in the flood period and normal period.

The Sacred Mountain and Holy Lakes located in the grand Yarlung Tsanpo Valley in the southern part of Ali Region, Tibet, that have been listed in the Preparation List of World Heritage Sites of Natural and Cultural Heritage include the Mount Gang Rinpoche, the Lake Mapam Yutso, the Lake Lana Tso. The four rivers originated in the vicinity are the Senge Kabab (the lion river), the langchen Kabab (the elephant river), the Macha Kabab (the peacock river), and the Tsangpo Kabab (the horse river), all which are the source of several world-famous rivers, such as the Indus River, the Ganges River, the Yarlung Tsanpo River and the Brahmaputra River.

In the ancient tradition of China and India, the Gang Renboqi mountain and its surrounding lakes and rivers had extremely important symbolic meanings, and they were the geographical landmarks indicating the center of the cosmological world. In the historical period, there were four ancient divine worldviews being formed around the Sacred Mountain and Holy Lakes in Ali, Tibet.

The first one is recognized by the local Bon religion of Zhangzhung culture in Ali area; the second one is the cosmological world center of anavatapta, which is recognized by Buddhism; the third one is the cosmological world center of Kunlun Mountain and Yao-chi, which is recognized by the ancient Chinese Book of Mountains and Seas; and the fourth one is the cosmological world center of Kailash (Kailasa), which was recognized by Hinduism. The four cosmography systems originated independently, formed their own special cognitive systems, and communicated and merged with other systems in history.

The integration of the Kunlun Mountain cosmological world view and the Buddhist Anavatapta cosmological world view happened around 1 500 years ago, and the new world view had a wide range of impact on ancient Chinese cosmography. In 1720, this world view was projected on the surveyed map, and the ancient subjective cognition was finally located into the concrete geographical objects of the Sacred Mountains and Lakes.

The Northwest Frontiers Military and Political Documents from the Song Dynasty is an important Heishuicheng document of Chinese secular literature collected in Russia. It has 109 pages, covering topics including grain and grass loan, Immigration, personal lawsuit, military supplies application, etc. Some of the geographical information contained in this document are not to be found in traditional historical records of the Song and Tangut (West Xia) frontiers. Based on analyzing the relevant geographic terms and information, the author finds out the new situation and new problems including the administrative system, crop transmission, traffics, city-village system and so on, in this paper. They are further used to enact the mutual confirmation between excavated documents and traditional historical records, to complete the missing parts in traditional historical records, and to enhance the understanding of the historical geography and social conditions of the Song and Tangut frontiers.

At the turn of the Twentieth century, Western municipal concepts and theories were gradually introduced into China along with the examples set by treaty port cities. Some traditional cities formed in the dynastic time also began to carry out modern municipal constructions. In this study, we take Ningbo old city as a typical case and focus on three ways of road improvements in the 1920s and 1930s: the demolition of the city wall, the filling of rivers and the removal of residential buildings. Based on earlier studies, we use large-scale old maps and local gazettes to restore and analyze the river channels and road networks. It shows that for the traditional cities in China, due to the lack of motivation and capital, even if the urban administrative districts had been set up, it might not be able to promote the conditions. On the contrary, it caused many social problems especially during the expropriation of construction land.

The Royal Road System was a road network of the Persian Empire, and routes of the Royal Road System have long been disputed among scholars. The records in Herodotus's History and Persepolis Administrative Archives reflect the general characteristics of the Royal Road which are also the criteria for identifying them from ancient roads. Although multidisciplinary research methods have provided assistances to the reconstruction of routes of the Royal Road System, they also caused many controversies. In general, routes of the Royal Road System in Anatolia, Mesopotamia, Syria and Armenia are relatively accurate. There is no way to infer routes of the Royal Road System in Egypt or Arabia. Routes of the Royal Road System in eastern satrapies are based on classical texts. However, the Royal Roads were not the general term for ancient roads in Persian Empire, and the diachronic changes of ancient roads are still very significant. With the help of the interpretation of cuneiform characters, archaeological excavations and scientific historical geography, the study of the Royal Road System may will overcome its dependence on classical texts research.

The Huaiyuan Posthouse of Canton was located in Xianzibu, Sai-kwan from the Ming to the early Qing Dynasties, which was the place where the Kwangtung Shi-Po-Si(广东市舶司) received the tribute ships and foreign envoys onboard those ships. It also functioned as the site for China-foreign tributary trade. With establishment of the Hoppo during the Kangxi reign, the Thirteen Hongs (factories) were assigned with the task of undertaking foreign trade. After many efforts, foreign tradesmen were allowed to rent commercial houses and set up factories in the Thirteen-Factory Street to the south of the Huaiyuan Posthouse. The Hongs were was managed by merchants. The Huaiyuan Posthouse was abolished in the late Kangxi emperor. The Thirteen factories basically replaced the functions of the Huaiyuan Posthouse. The essence of this shift from the Huaiyuan Posthouse to the Thirteen Hongs is the declined of the tributary system in Qing Dynasty and the rise of the Canton trade through the Hongs.

Historical records after the late Ming Dynasty generally claim that Nanwang has been the “water ridge” occupying a commanding height alongside the Huitong Canal, which is a section of the Grand Canal, since the Yuan Dynasty, and the key determining the success of the Huitong Canal in the Yuan and Ming Dynasties lies in choosing Nanwang “water ridge” as the water diversion hub. This paper proposes that this view is incorrect. Nanwang was originally the last remnant of Liangshanpo with a low-lying terrain. It began to silt up after Song Li diverted Wenshui River water to Nanwang for transportation in the early Ming Dynasty. In the Chenghua period of the Ming Dynasty, the pivotal position of Nanwang as the water diversion hub was determined. By then the mud and sand dug out and piled up on both sides of the river created a landform of heaped-up hill, hence the “water ridge” image in the eyes of people since the late Ming Dynasty. That is to say, the Nanwang “water ridge” was formed in the Mid Ming Dynasty as a result of natural sediment accumulation and artificial dredging. Based on this, this paper re-examines the reasons determining the success or failure of the Huitong Canal in the Yuan and Ming Dynasties and discusses the significance of the formation of the Nanwang “water ridge” on transforming the Huitong Canal from a river depending on the violent Yellow River for water supplies to the one that relies on the stable Wenshui River for water source in the middle of the Ming Dynasty as well as its far-reaching influence on the principle of Yellow River maintenance after the Mid Mind Dynasty.

It is possible to make a comparative calculation of the distances and routes recorded in ⅡT0214①∶130 and ⅤT1611③∶39, two Han dynasty slips from Xuanquan. The post at the easternmost point of Jiuquan Prefecture recorded in ⅡT0214①∶130 was not Biaoshi, but to the west of it; Biaoshi was a county belonged to Zhangye Prefecture at that time. The jurisdiction of Wuwei Prefecture recorded in ⅤT1611③∶39 was not in Guzang, but possibly in Fanhe. The main line of the “Southeast”courier route as seen in ⅤT1611③∶39 passed Tianshui and connected Anding, which was basically the conventionally acknowledged “North Route”from Chang’an to Hexi. This route also had a branch to Jincheng. Based on the above conclusions, the features of ⅡT0214①∶130 can be roughly reconstructed. The two slips of ⅡT0214①∶130 and ⅤT1611③∶39 commonly display a portion of the courier routes and administrative divisions of Hexi at a certain point in the Western Han dynasty.

Selecting the population data of settlement in 1934, 1982, and 2019 in Tumote plain, the distribution pattern evolution and its driving factors of settlement in the study area were analyzed through using GIS spatial analysis methods and combining qualitative and qualitative analysis. The results show that: during 1934-2019, the scale system of settlement in the study area was dominated by small settlement. The number and proportion of settlement with larger populations increased year by year and the population hierarchical structure showed a pyramid shape from “flat” to “long-tall”. The spatial distribution pattern of settlement showed the characteristics of agglomeration distribution as a whole. The agglomeration of large-scale settlements is not significant, and the distribution pattern of the other three levels of settlements changed from uniform to agglomeration distribution model. The population polarization in the study area was significant. The non-equilibrium development trend of the spatial distribution of the study area was obvious, showing signs of evolution from pole nucleus type to Pole-axis type. The spatial neighbor effect of network connection of settlement was significant, and the central urban area with a large population became a strong connection node. Terrain, river and traffic were the main driving factors for the evolution of the distribution pattern of the settlement in the study area during 1934-2019. The settlement showed strong spatial orientation to low altitude, and were significantly close to rivers, roads and towns. This study facilitates the clarification of the evolution of the settlement distribution patterns in the Tumut Plain in the past 100 years, and provides a certain reference value for the optimization and regulation of the spatial layout of local settlements.

On the lower reach of Damagou River in Tarim Basis, there was a desertified area once an oasis, it was about 80 square kilometers. On the ancient oasis area, many relics were scattered, such as Huyangdun Buddha temple ruins, Tuopulukedun Buddha Temple ruins, Big Graveyard, Huyang Graveyard, Kalaqin Ancient City, and Sipier Ancient City. The textual research shows the Kalaqin Ancient City was Kanchengzhen (Kanzhou) in Tang Dynasty, also the Phema City. In those years, the Kalaqin Ancient City was of a large population, commercially developed, and prosperous for Buddhism, but abandoned and desertified after 790 A.D. The Sipier Ancient City was the former capital of Qule State in Han Dynasty, but also abandoned and desertified in late Wei and Jin dynastys. The author analyzed two stages of desertification in the ancient oases and its causes.

The water area of Dianchi Lake is basically stable from Ming and Qing dynasties thanks to the annual dredging of the Haikou area. Still, seasonal change in water level is not completely solved due to frequent flood disasters. The deep rice was gradually planted systematically in Ming and Qing dynasties along the coast of Dianchi Lake to adapt to the seasonal changes in the waters in the Dianchi Lake, realizing the ecological coupling of low-field deepwater rice cultivation with seasonal changes in the water level. The situation changed completely in the late 1960s. With the construction of reservoirs and other water conservancy projects in the upper reaches of the Dianchi Lake, the lakeside and low fields were gradually drained, and the water environment for the deepwater rice was lost. From the point of view of the interactive relationship between the water environment of the Dianchi Lake and rice-growing ecology, if only the regional environment changes regularly for a long time, human beings may gradually turn “harm” into “benefit”, which is the proof of human wisdom to adapt to and make use of nature.

The anonymous Zuo Shanmu Fangpai Yaolan (Keys to Chinese Fir Wood Business and River Transportation) offers a slightly different view from previously discovered and rather common itinerary books on the Xin’an River-Qiantang River business journey. In addition to the place names and the distance along the way, it also includes many rules of wood business operation, which makes it a comprehensive business manual. Accordingly, we can explore the many facts of Huizhou merchants’ conducts in timber industry in the Qiantang River basin. The book contains business secrets of Hui-Xi merchants engaged in Qugang timber transportation and marketing, including five sections of continuous water routes along the way and a land route back to the hometown. On that basis, we can outline the route of Hui-Xi merchants engaged in Qugang wood business, and examine their related business norms more closely. From this point of view, the success of Hui merchants in the traditional times depended not only on their abundant wealth and higher cultural quality, but was also closely related to the relevant technologies and business norms they professed and spread.

Modern maps drawn using scientific surveying and mapping technology are precious historical geographical data source, directly showing land cover information in the past. Digitization is a necessary way to extract the historical land cover and its changes from old maps. This paper proposes an old map digitization method based on machine learning and image morphology analysis, and takes the “Eastern China: Shanghai” map as an example to elaborate its implementation process and verify the effectiveness. Results show that the method can fully utilize the color information and morphological information in the map, and extract the surface water information quickly and accurately in a semi-automatic manner. The proposed method can be applied to the digital extraction of land cover information with color characteristics in most color modern maps. It shows great potential to provide both data and method basis for accurately restoring land cover changes and understanding the evolution in man-land relationship since modern times.

The old map Fengmishan Zhaoken Sizhi Ditu collected in Germany library, showing mountain peaks, rivers, lakes, settlements, traffic lines and so on, is a valuable historical material. The map was drawn under the background of immigration and reclamation in the eastern Jilin Province in the late Qing Dynasty. It reflected the regional development in the frontier crisis. By interpreting the features on the piece of map, combining with the historical background outside of the map, it is helpful to understand the historical process of Jilin border area in the late Qing Dynasty.

In this paper, the historical data about drought and flood in the western part of the Jianghuai (江淮) region in Ming and Qing dynasties are sorted out, and quantified hierarchically by year and county. Then, by calculating the average grade value of drought and flood and the 10-year moving average value, the time series of dry-wet change in this area from 1450 to 1911 are reconstructed. The results show that there were six dry-wet phases in this area. From 1450 to 1490, the drought was mainly mild. From 1491 to 1545, drought and flood disasters occurred frequently, and the fluctuation of dry and wet climate was obvious. From 1546 to 1625, there were few droughts and floods, and the dry and wet conditions were relatively stable. From 1626 to 1710, moderate drought events were dominant, and the frequency of extreme drought events increased significantly. From 1711 to 1860, wetness dominated. From 1861 to 1911, dry-wet trend fluctuated and tended to be wet. Lakes in this region were also affected in dry and wet stages.

Diplomatic staff of the Western powers were permitted to reside in Beijing after 1860. The number of city maps of Beijing drawn by Westerners increased and their accuracy improved significantly. The types and uses of maps were also greatly enriched. This paper first systematically organizes the historical material of these maps, and then classifies them into three categories according to their uses and modes of publication. By taking the perspective of the history of cultural exchanges and using the method of textual analysis in literary studies, we look at these maps as a reflection of Sino-foreign relations in the late Qing Dynasty and the image of Beijing perceived by Westerners.

In historical periods, Chinese emperors paid great attention to local precipitation and required local government to report precipitation to the central government regularly. This paper mainly uses the Xunhua (循化) archives to investigate the practice of Yuze (***) reporting system in counties in the late Qing Dynasty. There were reports every ten days and monthly ones. Both are required to record daily information including the weather condition, precipitation, begin-and-end time of rainfall. What's more, there was a special report to record rain in summer and snow in winter. It is an important guarantee to ensure the accuracy of Yuze (雨泽) reports to check the record format, time, clients and information of local government by sensior officials from prefectures, provinces, and ministries. In addition, the report from agrarian officials was also one of the sources of reports of rainfall and harvest.

Abstract: In the middle and late Northern Song Dynasty, Caodong school as one of the Zen began to revive. Furong Daokai (芙蓉道楷) was a monk of importance in Caodong School (曹洞宗) during Northern Song Dynasty. This essay, based on the inscription of Daokai and relevant materials, restores Daokai's history of life and the basic process of his preaching Buddism. The region from Suizhou(随州) up north to the surroundings of Dongjing (东京) became a significant area for Daokai and his dharma heirs. Owing to Daokai's influence, his followers took up the positions of numerous famous monasteries and mountains, which was a turning point in the trend of Caodong School. Although Daokai was demoted when in Dongjing, this was due to his personal clash with Tan Zhen. Because of the relationship between Daokai and monks and laymen in Dongjing, Daokai's relegation exerted no negative influence on the promotion of Caodong School in Dongjing immediately. But in the long run, the monks from Dahongshang were no longer appointed abbots of the monasteries in Dongjing. The Caodong school lost the Dongjing as their preaching area, and turned to preach in south of the Yangtze River.

This paper compares the surviving and excavated documents and points out that the commandery’s capital county was the highest-ranking among the counties belonging to the same commandery in the Han Dynasty. Based on the rank and order of a commandery’s counties recorded in the Statutes on Salaries (Er Nian Lü Ling: Zhi lü) from Zhangjiashan Han Slips, we can analyze the governance of some commanderies in the early Western Han Dynasty. According to the Statutes on Salaries, the capital of Longxi Commandery in the early Western Han Dynasty was Shangli County; Shang Commandery’s capital was Gaonu County, and the capital of Beidi Commandery was Panyang County. Besides, the capital of Hanzhong, Hedong, and Hainai Commanderies in the early Western Han Dynasty can also be further inferred by the Statutes on Salaries. This document’s value in the study of capital counties in the early Western Han Dynasty needs to be emphasized.
