Under the influence of global economic transformation, China's economy has turned into a medium-low growth pattern, and the spatial distribution of population has also undergone structural changes, and more and more cities are facing the challenge of contraction. At present, most of the shrinkage phenomena in China occur in villages and towns, especially in small towns with exhausted resources. In this paper, Sanhui Town, Hechuan District, Chongqing, a typical resource-based small town, is selected as the research object. Firstly, the development process and influencing factors of Sanhui Town are sorted out, and the problems of population contraction, economic development and land use in Sanhui Town are summarized. Then, the theoretical concept and planning strategy of "smart contraction" are put forward. The research results not only seek solutions to the practical problems of shrinking resource-based small towns, but also provide a way of thinking for the development of other towns in the future.
