Ecosystem Evaluation of Plateau Lakes Based on Hierarchical Analysis:A Case Study of Shahu Lake
Based on the ecosystem evaluation system of lakes at home and abroad,this paper proposed"3 elements and 17 indicators"as the indicator system for the evaluation of the Shahu Lake ecosystem.The evaluation results showed that the score of"overall function"in the evaluation system of Shahu Lake ecosystem was low,the score of"social impact"was high,and the overall ecosystem of Shahu Lake was in a general stable state.It was suggested to carry out ecological management of the lake in terms of controlling the quantity and quality of water transferred from the Yellow River,reducing industrial and agricultural pollution,and improving the water quality of the lake,so as to provide theoretical support for the ecological management,protection and restoration of the lake.
