摘要： 以上海东区水质净化厂尾水深度处理人工湿地池为例，探究其水质等环境因子与蚊幼孳生的关系.使用综合污染指数（P）法及有机污染指数（A）法对2017年5月至11月内湿地池水质进行了评价；使用勺捕法于同期内对湿地池中共14个样点的蚊幼孳生情况进行了监测.分析表明：①上海市东区水质净化厂湿地池水质优于地表水V类标准；②淡色库蚊蚊幼密度在水质综合污染指数较高的水中更大，最高可达143.1条/勺；③淡色库蚊蚊幼密度在5月至8月内较高，且随着温度的降低而减少；④淡色库蚊蚊幼密度在可受到阳光直射的区域显著小于长期受遮蔽的区域（p<0.05）；⑤淡色库蚊蚊幼密度在叶绿素a浓度偏高时较小，过量的浮萍覆盖可抑制蚊幼孳生.

Abstract: In this study, a constructed wetland for advanced treatment of tail water at the Shanghai East Water Purification Plant was taken as an example to explore the relationship between environmental factors, such as water quality and mosquito (Culex pipiens pallens) larval breeding. The comprehensive pollution index (P Value) method and organic pollution index (A Value) method were used to evaluate the water quality of wetland from May to November of 2017. The breeding status of mosquito larvae at 14 sample points in the wetland were monitored by the standard dipping method during this period. The subsequent analysis showed that:① The water quality of the wetland was better than Class V of the environmental quality standard for surface water; ② The larval density was higher in water whose P Value was equal to or greater than 143.1 per spoon; ③ The larval density was high between May and August and declined with the decrease of temperature; ④ The larval density was significantly lower in areas where the water surface could be exposed to direct sunlight (p<0.05); and ⑤ The larval density was small when the concentration of Chlorophyll a was high, and excessive duckweed coverage can inhibit mosquito breeding.

Key words: constructed wetland, water quality, mosquito larval breeding
