Abstract:

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.
