As the portal lake of Xinjiang, China, Ebinur Lake is the lowest wash and the center of water and soil in south-western Junggar basin. Its ecological environmental problems seriously threatened due to the land use and land cover change of Ebinur Lake to the sustainable development in the northern slope economic zone in China, even threatened the safety and smooth of the Asia—Europe continental bridge. It is significant for reasonable formulation of environmental policy of northwestern China to explore the land use and land cover change of Ebinur Lake and its temporal variation characteristics of ecosystem service value. This study took the typical Ebinur Lake for the study site. The temporal variation characteristics of ecosystem service values were studied by using five temporal Landsat-TM multispectral remote sensing images from 1990 to 2011 and the computational formula of Costanza ecosystem service value as well as the sensitivity analysis and Chinese land ecosystem service value per unit area created by Xie Gaodi. The conclusions are as follows: in 1990—2011, the land use of Ebinur Lake showed an increasing trend; the degree of land use presented the tendency of increase; during the research period, the ecosystem service values showed the general rose, which increased 230 million Yuan from 16.169 billion Yuan to 16.169 billion Yuan; woodland, grassland, water area ecosystem service values are the main part of the ecosystem services, accounting for more than 84.19% of the whole system; the overall ecological environment quality of Ebinur Lake is showing a worsening trend; although the expansion of basin for land use types with high ecological value area is helpful for the improvement of the quality of the whole river basin ecological, its overall ecological environment is still relatively weak and needs to be improved.
