不同的水质评价方法在澜沧江源区水环境质量评价中的应用

The Application of Different Water Quality Evaluation Methods in Water Quality Assessment of Lancang River Source Region

摘要: 根据2012年澜沧江源区水质监测结果，利用指数评价法、水质标识指数法、灰色关联分析法对澜沧江源区水质进行评价，并结合评价结果对这几种水质评价方法进行分析比较。结果表明：综合污染指数评价法、综合水质标识指数法能一定程度上平衡污染因子对水环境质量的贡献度，较为真实的反应水体的整体状况；灰色关联分析法可作为重要的水环境质量评价分析的辅助方法。

Abstract: According to 2012 Lancang River source region water quality monitoring results, the water quality in the Lancang River source region is evaluated by using exponent evaluation, water quality identification index method, gray correlation analysis method. Combining with the evaluation re-sults, these methods of water quality evaluation are analyzed and compared. The results showed that the comprehensive pollution index method and water quality identification index method can balance the contribution of pollution factor to the water environment quality, the overall situation is more real reaction to the water bodies; gray correlation analysis method can be used as an im-portant adjunct water environment quality assessment analysis.
