摘　　要：指出了地表水环境质量评价主要有单因子评价、污染指数评价和不确定性评价等方法。采用单因子评价、灰关联分析和内梅罗指数法对H市地表水环境质量作出了评价,共选择9个指标作为评价因子,分别对33个水质样品进行了评价,并将评价结果进行了对比。结果表明:3种评价方法的水质评价结果,在污染小的河流相差较大,在污染河流中较为接近。建议采用单因子评价和灰关联分析结合的评价方法对地表水环境质量进行评价。Methods of the environment quality evaluation of surface water mainly include the single factor evaluation,the pollution index evaluation and the uncertainty evaluation.In this article,methods of the single factor evaluation,the grey relational analysis and the improved Nemerow index are adopted to evaluate the environment quality of surface water in H city.The article selects 9indicators as evaluation factors to evaluate 33 samples of surface water in H city and the three evaluation＇s results are compared.The results show that the testing results of different evaluation methods are similar in polluted river while quite different in slightly polluted river.This article suggests that the combination of single factor evaluation and grey rational analysis method should be adopted in the environment quality evaluation of surface water.
