内梅罗水污染指数法在太湖水质评价中的适用性分析

Analysis of applicability of Nemerow pollution index to evaluation of water quality of Taihu Lake

为了有效地服务于水资源保护和管理,运用内梅罗水污染指数法对太湖历年水质进行评价。结果:该方法的评价结果与太湖的宏观治理进程较为吻合,相比单因子评价法能够更加简明直观地反映综合水质状况,且与湖库营养状态评价结果之间具有显著的线性相关性。通过对比分析,认为内梅罗水污染指数法在太湖水质评价中具有较好的适用性。

For more effective water resources protection and management, the Nemerow pollution index was used to evaluate the water quality of Taihu Lake overmany years. The evaluation results of this method agree with the macro governance process in Taihu Lake. The proposed method can be more concise and intuitive than the single factor evaluation method in reflecting the comprehensive status of the water quality. Furthermore, the evaluation results of the proposed method have a significant linear correlation with the results of eutrophication evaluation of lakes and reservoirs. Comparative analysis shows that the Nemerow pollution index has wide applicability to the evaluation of the water quality of Taihu Lake.
