Abstract: The 18th National Congress of the Communist Party of China put forward the new concept of “production-living-ecological spaces”, which was used as a theoretical basis to analyze and study the spatial pattern and change characteristics of Sichuan province from 2000 to 2018. The results show that the production space is mainly distributed in the eastern part of Sichuan, while the southern part is less distributed. The expanded areas are mainly distributed in the central Ganzi Tibetan autonomous prefecture, northwestern Aba Tibetan and Qiang autonomous prefecture, and central Zigong, while the reduced areas are mainly distributed in northern Aba Tibetan and Qiang autonomous prefecture, central Chengdu, and southwestern Ya'an; Living spaces are mainly distributed in urban areas of each city, especially in Chengdu. The expansion area is mainly in the central and eastern part of Sichuan province, and the expansion is obvious in Chengdu, Deyang and other places. The reduction area is scattered and the reduction is not obvious; The ecological space is mainly distributed in the northwest and south regions of Sichuan, showing a distribution pattern of “high in the west and low in the east, high in the north and low in the south”. The expanded area is mainly scattered in dots in urban areas of each city, and the reduced area is concentrated in the city center, especially in the middle east of Chengdu, the middle of Zigong and other places.
