Abstract： As the most important link in the Middle Route of the South-to-North Water Diversion Project in China， the changes in the eco-environmental geology of Danjiangkou Water Source affect the economic development and people's life safety of the cities along the South-to-North Water Diversion Terminal. Taking the Danjiangkou Water Source as the research object， this paper systematically evaluates the environmental geology， the vulnerability of geological disasters， the importance of ecological protection， the suitability of agricultural production， and the suitability of urban construction in the study area， and explores the temporal and spatial changes of the regional eco-environmental geology.

Keywords： eco-environmental geology; suitability; Danjiangkou Water Source
