基于等效数值评价法的湖库营养状态评价分析

Lake (reservoir) nutrition status evaluation based on equivalent value method

根据国家湖泊(水库)营养状态评价标准及分级方法,运用等效数值评价法,建立湖库营养状态综合评价的等效数值模型,以云南省9大高原湖泊为例,对滇池等湖泊营养状态进行综合评价,并与主成分分析法及指数评价法评价结果作对比分析。结果表明该模型满足评价精度要求,是一种湖库营养状态综合评价的新方法。

In accordance with the China evaluate standard and classification method on lake（reservoir） eutrophication,equivalent value model is established to make nutrition status comprehensive evaluation for the nine major plateau lakes of Yunan Province,including Dianchi lake.The evaluation results were compared with that out of main component analysis method and index method,demonstrating that this model meets the accuracy requirements,and is a new method for comprehensive evaluation of lake（reservoir） nutrition status.
