上海市水源地水质综合评价方法的探讨

The discussion of comprehensive evaluation model for water quality in Shanghai water resource area

基于2005年至2007年上海市陈行水库和青草沙水源地的监测资料,应用基于组合权重法的水质综合评价模型对水质状况进行了综合评价。并将综合评价结果与单因子评价结果进行比较分析。研究结果表明:基于组合权重法的水质综合评价模型简便、适用,利用样本信息较为全面,能够实现对水质客观、准确、量化的分类和排序,是一种较为有效的水质评价方法。

A comprehensive evaluation model for water quality based on combined weights is used to evaluate the water quality of Shanghai Chenhang water resource area and Qingcaosha beach water resource area based on the investigation data from 2005 to 2007.By the comparison between the comprehensive evaluation model and the one-factorial evaluation model,the research results show that the comprehensive evaluation model is simple and suitable,it takes advantage of more comprehensive message from water samples,the grades,quality of water samples can be classed well and indexed truly,it is an effective evaluation model for water quality.
