Taking the Tianshan area of Xinjiang as the study area, we analyzed the changes of the ecological-production-living spaces and ecological and environmental effects, so as to provide a scientific basis for the optimization of the spatial pattern of the ecological-production-living spaces as well as the regional ecological and environmental protection in the region. Based on the land use data of 1980, 2000 and 2020, the land use transfer matrix, ecological environment quality index and ecological contribution rate were used to analyze the spatial and spatial distribution and characteristics of the spatial and temporal changes of the ecological-production-living spaces and ecological environment quality of the region from 1980 to 2020, and the spatial and temporal distribution of the ecological-production-living spaces and ecological environment quality of the Tianshan area were analyzed from 1980 to 2020. The spatial differentiation of the ecological-production-living spaces is remarkable. With the Tianshan area as the boundary, the production and living land is distributed on the north and south sides of the mountain range, and the production and living land is rapidly increasing and expanding; the ecological land is the most important type of land in the northern slope of the Tianshan area, with a wide distribution area, which is mainly located in the Bayin'guoleng Mongol Autonomous Prefecture, the Aksu region, and the city of Turpan. The ecological quality of the Tianshan area has experienced a slow and then intensified reduction in time, and the ecological quality of the environment will be minimized by 2020; Spatially, it has a spatial distribution pattern of "high in the north and low in the south". The ecological environment quality deteriorates in the southern part of Aksu, the southern part of Bayin'guoleng Mongol Autonomous Prefecture, and the Turpan area, while the ecological environment quality is high in Urumqi, Changji Hui Autonomous Prefecture, and Ili Kazakh Autonomous Prefecture. The ecological environment quality in the Tianshan area shows a decreasing trend, and the degradation of pasture ecological land and water ecological land into other ecological land is the main factor of ecological environment deterioration.
