Abstract: In order to build a great chapter of Yunnan in beautiful China and build a well-off society in an allround way, the paper took Yunnan Province as a spatial hierarchy to overcome the traditional emphasis on single factor evaluation method. The author constructed a comprehensive evaluation method and used GIS to analyze the ecological environment and spatial characteristics of Yunnan Province. On this basis, the author put forward ideas and countermeasures for ecological civilization construction in Yunnan. The results showed that in Yunnan Province, environmental capacity was at medium level, eco-environment was more vulnerable and had great significance, natural disasters occurred frequently, and eco-environment spatial differentiation was more obvious. The province could be divided into three functional areas, which were the overall balance area, the efficiency dominant area and the environmental dominant area.
