摘要
为探讨CCME WQI在我国水资源管理中的适用性,以四个典型水功能区的水质评价为例,对比分析了评价法CCME WQI与我国常用的内梅罗指数和单因子指数评价法的评价效果。结果表明,当无污染物超标时,三种评价方法的评价结果一致;当超标污染物较少时,CCME WQI与单因子指数评价法的评价结果基本一致,且均比内梅罗指数评价法的评价结果严格;当超标污染物较多时,CCME WQI评价法的评价结果比另外两种方法的评价结果严格。总体来看,CCME WQI评价法适用于我国的水质评价。
To examine the suitability of CCME WQI in Chinese water resources management,we select four typical water functional areas to compare the difference among CCME WQI and other common water quality evaluation methods,such as Nemerow index,single factor index.The results show that when there is none overproof pollutant,the conclusions of these three methods are identified;when the proportion of overproof indicators is low,the conclusions of CCME WQI and single factor index are similar,while the Nemerow index is more loose;when the proportion of overproof indicators is high,the result of CCME WQI is more strict than the other two methods.In general,CCME WQI is suitable in the water quality assessment of China.
