| 摘 要： | 根据对南湖公园水质的监测数据建立评价因子集，根据环境质量标准的5个等级建立评价等级集，选择降半梯形分布来确定隶属函数，建立模糊关系矩阵，采用超标倍数赋权法确立权重系数，构造权重系数矩阵，将模糊矩阵和权重矩阵进行合成，得出南湖公园水质综合评价结果。结果表明：南湖公园的水质基本达到Ⅴ级标准，基本满足地表水水域环境功能，但部分娱乐用水区水质存在污染。与其他方法的比较结果表明，该模糊综合评价法较好地解决了质量分级归属问题，采用超标倍数赋权法确立权重得到了比较客观的结果。

| Abstract: | The evaluating factor congregation was set up according to the monitoring data of Nanhu Park water quality.The evaluating grade congregation was established based on 5 grades of environmental quality standard.The subordinate function was confirmed to establish fuzzy relation matrix by selecting the falling semi-trapezoid distribution.The weight coefficient was confirmed to construct weight coefficient matrix by using super-standard multiple weight method.And the comprehensive evaluating results on water qua... |
