摘　　要：运用模糊评价对巢湖市饮用水水源地保护区水质进行综合评价,通过确定8个主要影响因子的权重和隶属度,结果表明,主要超标指标为TN、TP,水体富营养化严重;6、7、8月随入湖水量进入的污染物多,12月水体自净能力差,水质恶化严重。同时,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突出影响水体的主要污染因子,具有从严性,而模糊综合评价充分考虑了多个因子对水体的影响其结果更加准确、客观,因此可为水源地保护区的水质规划与管理工作提供科学的参考依据。Evaluation of fuzzy comprehensive was used for evalutating comprehensively the drinking water source protection area of Chaohu city.Evaluation results were obtained by weights and membership of 8 main factors.The results showed that the main exceeded targets of Chaohu Lake were TN and TP and serious eutrophication.Contamination were more than other months with lake water content in June,July and August,the ability of water substance self-purification was poor in December and the water quality serious deteriorated.Compared the results of fuzzy comprehensive evalution with single-factor evalution＇s,it reflected that single-factor evaluation stressed the main of water pollution factor and strict.The fuzzy comprehensive evaluation stressed that a number of factors fully into account the impact on water and was more accurate,objective.So it could provide scientific reference for water quality program and management of drinking water source protection area.
