Abstract

In recent years, regional climate change and the intensification of human activities have made the problem of water shortage particularly prominent. It is of great significance to conduct in-depth research on the ecological environmental impact and evaluation methods caused by the use of regional water resources. Based on the characteristics and actual conditions of Delingha City in the northwest inland river region, this article established the Northwest in terms of water conservation, vegetation stability, soil conservation, and soil quality improvement in accordance. The ecological environment impact assessment index system of Delingha City in the inland river area is combined with the analytic hierarchy process and cloud theory model to establish an evaluation model. The purpose is to scientifically and reasonably evaluate the ecological environmental impact of Delingha City in the northwest inland river area. The results show that the overall impact on the ecological environment of Delingha City is the third level and is in a good state, in which water conservation and soil quality improvement are in a good state, and the other two criterion levels are in a normal state, and the annual precipitation accounts for a larger weight.
