The southeast coastal area, where several major urban agglomerations are concentrated in, is the main engine of national economic growth. Studying the natural development context of coastal cities will help to improve the urban scale structure, strengthen the relationship between urban space and surrounding areas as well as bring enlightenment for the coordinated development of regional economic belt. Taking Huzhou as an example, this paper studies the evolution of the natural system of coastal cities in the Taihu Lake River Basin. This research focuses on the formation of urban natural spatial pattern based on the city's natural development mechanism and try to sum up the traditional urban development mode through combining the evolution data of urban natural system in historical period, in order to put forward scientific theory and practical basis for the protection, construction and inheritance of traditional urban natural base in China. Through the field survey and graphic analysis, this article makes an in-depth analysis of the urban development and the evolution of natural system in Huzhou from three aspects: (1) the Urban Development of Ancient Huzhou; (2) the natural urban system of Ancient Huzhou; (3) the exploration of the natural urban development model of Huzhou, and the conclusion is that the relationship between the city and the natural system of Huzhou shows a spiral rise in the process of evolution.
