| 摘 要： | 从众多的水环境质量评价方法中,选取代表性的指数评价法、灰色评价法、层次分析法和模糊数学法进行介绍,然后运用这些方法对青海湖入湖河流2010年监测数据进行评价。经过对比分析评价结果发现,本次评价研究中单因子评价法过于悲观,水质综合污染指数法具有不可比性,模糊数学法具有不准确性。四种水环境质量评价方法中,灰色评价法和层次分析法是最适合该流域的评价方法,指数评价法和模糊数学法可以作为其必要的补充。 |

| Abstract: | It was introduced exponent evaluation,gray evaluation,AHP and fuzzy evaluation from many of the water environment quality evaluation methods,and then evaluated the monitoring data of rivers flowing into Qinghai Lake in 2010 by using these four above-mentioned methods.By comparison,analysis and evaluation,it was found that single factor evaluation method was too pessimistic,water comprehensive pollution index was not comparable,and fuzzy evaluation was not accurate.So a conclusion was reached that among these four kinds of water environmental quality assessment methods,grey evaluation and AHP were the most suitable ones for the evaluation of this basin;exponent evaluation and fuzzy evaluation could be used as its essential supplement. |
