As the head of the canal of the middle route of the South-to-North Water Transfer Project and the location of Danjiangkou Reservoir in Henan province, analyzing the impact of the expansion of surface water in Xichuan County on the production-living-ecological space and ecological migration is of great significance to regional ecological protection and development.This study uses the Google Earth Engine cloud platform and uses 1631 Landsat remote sensing images to dynamically analyze the evolution of Danjiangkou Reservoir from 2000 to 2020. By constructing an production-living-ecological space classification system, it analyzes the impact of Danjiangkou Reservoir expansion on Production-living-ecological space of Xichuan County. It also has a influence of the evolution of the pattern and the impact of ecological migration. The results show that: (1) From 2000 to 2020, the ecological space area of Xichuan County fluctuates up, the production space area gradually decreases, and the living space area continues to expand. (2) The surface water area of Danjiangkou Reservoir in Xichuan County has fluctuated and increased from 2000 to 2020. The expansion of Danjiangkou Reservoir has increased the submerged area of Xichuan County by 181.67 km2. (3) The expansion of the ecological space in Xichuan County, especially the expansion of the Danjiangkou Reservoir water body, took up 181.67 km2 of ecological and living space, reduced the carrying land area and increased the pressure on the carrying population, resulting in 162 000 ecological immigrants in Xichuan County.
