改进水环境质量评价方法对于提高水环境管理水平具有重要意义。根据传统灰色关联分析原理，采用“中心化”的灰色关联无量纲化处理方法，对丹江口流域2012年河流中11个典型断面水体污染因子进行评价。结果表明，参评的11个断面中有9个符合地表水Ⅱ类水质标准，2个断面符合地表水Ⅳ类水质标准，整体水质满足国家南水北调水源地水质标准要求，改进的灰色关联分析方法在评价水质时较为科学、合理。%To improve the evaluation methods of water environmental quality has very important significance for improving water environment management level. According to the principles of traditional gray correlation analysis, the study selected the actual concentration measurement data of pollution factors as the evaluation object, which belonged to 11 typical sections of the rivers of Danjiangkou valley of 2012. Results showed that involved in the evaluation of the 11 sections there were 9 affiliated standardⅡof national surface water quality, and the rest two sections affiliated Ⅳ, with meeting the requirements of national diversion demarcated to the water sources. The improved Grey Correlation Analysis is rational in the process of water quality evaluation.
