摘要
以中国10个典型城市2013年实测地表水水质资料为基础,运用内梅罗指数法、均值法、地表水质指数法(SWQI)3种评价方法对城市地表水质进行综合评价。结果表明:就评价指标而言,3套指标方案评价结果显著相关,最佳指标为DO、COD_(Cr)、NH_3-N、TP;就评价方法而言,内梅罗指数法是3种方法中的首选方法,SWQI法评价结果表现为过保护,均值法不能突出较差水质指标的影响。
Based on the monthly water quality data of 10 typical cities in 2013, the status of urban surface water quality was comprehensively evaluated with three assessment methods, including Nemerow index method, mean value method, and surface water quality index （SWQI） method. The research results showed that for evaluating indicator, there was a significant correlation in the evaluate results by the three methods, and the best evaluation indexes were DO, CODcr, NH3-N and TP. In terms of evaluation method, Nemerow index method was the best one among these methods; the results evaluated by SWQI method represented as overproteetion, which could not reflect the real status ; and the water quality assessed by mean value method could not highlight the effect of bad water quality index.
