| 摘 要： | 运用模糊综合评价和单因子评价对巢湖水质进行综合评价,通过确定湖区12个监测断面的8个主要影响因子的权重和隶属度得出评价结果：巢湖主要超标指标为TN、TP,12个断面中水质为劣Ⅴ类的所占比例较大,巢湖水质总体状况差,富营养化严重,其中西半湖污染重于东半湖。将模糊综合评价结果与单因子评价结果进行对比分析,结果表明单因子评价在判定水质级别归属时具有从严性,而模糊综合评价可以有效地解决在水质级别划定时由于中介过渡引起的亦此亦彼性,能为制定巢湖的环保政策和水污染防治规划起到借鉴作用。

| Abstract: | Evaluation of fuzzy comprehensive and single factor were applied in Chaohu lake water quality by comprehensive assessment.Evaluation results were obtained by weights and membership of 8 main factors of 12 monitoring sections in lake.The main exceeded targets of Chao Lake are TN,TP,and water quality is the level V for the large proportion in the 12 monitoring sections.Overall water quality was poor state and severe eutrophication,thereinto the west half of lake pollution is more important than the eastern ha... |
