摘　　要：2019年1—12月对常州市武进区西南部的滆湖开展了底栖动物监测与分析,并通过BPI生物学指数和Shannon-Wiener多样性指数对滆湖进行水质生态评价。结果表明:共鉴定出底栖动物14种(属),其中摇蚊幼虫类种类最多,共8种,寡毛类5种,软体动物类1种;主要优势种为红裸须摇蚊(Propsilocerus akamusi)、太湖裸须摇蚊(Propsilocerus taihuensis)、克拉泊水丝蚓(Limnodrilus ciaparedeianus)和梨形环棱螺(Bellamya purrificata)。2种指数评价结果显示,滆湖水质现状处于中度污染时期,属于富营养化过程的初中期。From January 2019 to December 2019,the zoobenthos were monitored and analyzed in Ge Lake,water source area of Wujin District,Changzhou City.The ecological evaluation of water quality in Ge Lake was conducted through BPI Biological Index and Shannon-Wiener Diversity index.The results showed that 14 species(genus)of zoobenthos were identified in the whole 12 months of the year,of which the species of the genus Chironomidae were the most,totaling 8 species,5 species of Oligochaetes and 1 species of Molluscs.The main dominant species were Propsilocerus akamusi,Propsilocerus taihuensis,Limnodrilus ciaparedeianus and Bellamya purrificata.The results of the two index evaluations showed that the water quality of Ge Lake was in a period of moderate pollution,which belongs to the early and middle stages of the eutrophication process.
