Research on ecological environment impact assessment based on PSR and cloud theory in Dari county, source of the Yellow River

In order to reasonably evaluate the ecological environment of Dari County in the source region of the Yellow River, the characteristics and actual conditions of Dari County's ecological environment are taken into account, and the principles of representativeness, scientificity, operability and...
