| 摘 要： | 通过均值法、断面比例法、均值-灰色关联分析法、灰色关联分析-断面比例法、均值-模糊综合评价法、模糊综合评价-点位比例法6种方法对2013年全国地表水七大流域水质分别进行评价。结果表明:均值法和点位比例法差别在于多数流域出现水质类别变化,但变化方向并不一致;引入灰色关联分析和模糊综合评价后水质评价结果明显改善,但模糊综合评价在适用性和评价精度上更有优势。

| Abstract: | Evaluation of surface water of seven river chains nationwide respectively by Averaging method, Section ratio method, mean value of the grey Relational analysis, Averaging method, mean value of fuzzy comprehensive evaluation method, Fuzzy Comprehensive Evaluation, Fuzzy Comprehensive Evaluation-Section ratio method shows that: the difference between Averaging method and Section ratio method is that most of river chains water quality grade change, but goes in different direction; that according to Grey Relational Analysis and Fuzzy Comprehensive Evaluation, water quality grade improves, and Fuzzy Comprehensive Evaluation has advantage in applicability and accuracy. |

| Keywords: | Single-Factor evaluation method Averaging method Section ratio method Grey relational analysis Fuzzy comprehensive evaluation |
