Based on the perspective of ecological-production-living function, with 2019 as the time section, and based on the land use data and socioeconomic data, the variation coefficient method, TOPSIS model, comparative advantage degree and GIS spatial technology are used to identify the spatial function characteristics of Anning City, optimizing and reconfiguring its development pattern, in order to provide a decision basis for urban function positioning and territorial space development and protection in Anning City. The results show that: (1) The streets with the strongest evaluation of production function in Anning are distributed in the streets in the southern part of the study area and Cao Pu street; the areas with the strongest evaluation of living function are Lian Ran street and Jin Fang street in the central city of Anning; the areas with high evaluation of ecological function are Bajie street and Qing Long street.(2) Forming five functional optimization zones of land space in Anning City and analyzing the characteristics of each functional area and orienting different street development directions with balanced development of land space.
