为了更好地治理大冶湖水环境，有必要对大冶湖典型湖段不同时期的水质进行评价。基于2013年大冶湖2个典型站点全年的水质监测值，依据大冶湖管理目标和单因子法选择6个污染因子，利用熵值理论和可变模糊集模型，对大冶湖年内水质状况进行了综合评价。评价结果表明：磊山站水质基本接近Ⅲ类，各次监测水质变化幅度不大；大冶站水质介于Ⅲ到Ⅴ类之间，变化幅度相对较大。同时，结合大冶湖流域的水位、雨量等水文要素，对评价结果进行模型解释，随后，将可变模糊综合评价结果同单因子法进行了对比。最后根据评价结果提出对大冶湖的治理建议，建议加强大冶湖汛期前后入湖水质达标排放监测管理。

For better treatment of water environment in Daye Lake ,it is quite necessary to evaluate water quali-ty of typical section of Daye Lake in different periods .Using the datas of water quality monitoring in two typi-cal stations in Daye Lake in 2013 ,based on the lake's management target and single factor method ,six water quality evaluation indexes are chosen .A water quality evaluation model is established on the basis of variable fuzzy sets and entropy theory,according to the model,the water quality in different sections and different peri-ods are evaluated.The results show that the water quality in Leishan station is nearly closed to grade Ⅲ,and there is a little change .The water quality in Daye station is between grade Ⅲ and gradeⅤ, the result has changed relatively greatly.Meanwhile, the analysis combined with the precipitation and water level of the Daye lake Region are discussed.Furthermore,variable fuzzy set evaluation and single factor evaluation method are compared.Finally, according the evaluatin results, it is suggested that the monitoring management of drainage standard in Daye Lake be strengthened before and after flood period .
