基于层次分析法的高原湖泊生态系统评价——以沙湖为例

Ecosystem Evaluation of Plateau Lakes Based on Hierarchical Analysis: A Case Study of Shahu Lake

基于国内外湖泊生态系统评价体系,提出了“3要素17指标”作为沙湖生态系统评价的指标体系。评价结果显示,沙湖生态系统评价体系中“整体功能”赋分较低,“社会影响”赋分较高,沙湖生态系统整体处于一般稳定状态。建议从控制黄河输水量及水质、降低工农业污染、提高沙湖水质等方面开展湖泊生态整治,以期为沙湖生态治理、保护和修复提供理论支持。

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.
