不同水质评价方法的适用性研究——以沙湖为例

Availability of Different Water Quality Assessment Methods:Taking Sand Lake for Example

分别运用综合指数评价法、模糊综合评价法、灰色关联度法对沙湖在2009年的16个监测点的水质状况进行评价,对不同评价方法的评价结果进行比较分析,综合考虑各方法的评价结果,得出关于沙湖水质比较准确、客观的结论。最后,比较3种方法的优、缺点,提出了将不同方法相结合更能真实地反映水质状况的结论。

Comprehensive index method,fuzzy comprehensive evaluation and grey relational analysis are introduced in this paper to evaluate water quality of 16 monitoring sites for Sand Lake in 2009,the results of different methods are compared and analyzed,the objective conclusions are reached after a comprehensive consideration.Finally,the advantages and disadvantages are proposed,the conclusion is that the combination of these different methods can truthfully reflect water quality assessment.
