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.

Key words: Dianchi Lake, water area, water level, low field, deepwater rice
