摘　　要：为了解板桥水库大型底栖动物群落结构动态特征并对其水质进行生物学评价,在该水库设置15个采样点,于2014年1—11月按季节进行调查.结果表明:在板桥水库采集到大型底栖动物17种,隶属于3门4纲5科,其中摇蚊幼虫8种、寡毛类4种、软体动物5种.铜锈环棱螺、河蚬、苏氏尾鳃蚓、粗腹摇蚊和雕翅摇蚊为现阶段板桥水库的重要物种.大型底栖动物密度、生物量和多样性指数存在空间和时间差异性.ANOSIM分析显示,大型底栖动物群落结构在不同区域和季节间均存在显著差异,其主要贡献物种为雕翅摇蚊、粗腹摇蚊和苏氏尾鳃蚓.经丰度-生物量比较曲线(ABC曲线)分析,板桥水库大型底栖动物群落稳定,结合物种多样性指数、生物学污染指数(BPI)和Hilsenhoff生物指数(BI)评价结果,板桥水库的水质处于轻度污染水平.In order to demonstrate macrobenthic community structure dynamics and conduct a biological evaluation of water quality in Banqiao Reservoir,we collected seasonal samples from January to November 2014 across 15 sampling sites. A total of 17 species belonging to five families,four classes,and 3 phyla were identified,including 8 chironomidae,4 oligochaeta and 5 mollusc. Bellamya aeruginosa,Corbicula fluminea,Branchiura sowerbyi,Pelopia sp. and Glyptotendipes sp.were the important species in Banqiao Reservoir. The total density,biomass and biodiversity of macrobenthos showed significant spatial and temporal differences. ANOSIM analysis indicated that the macrobenthic community structure also differed significantly among regions and seasons,and the main contributing species were Glyptotendipes sp.,Pelopia sp. and B. sowerbyi. The abundance-biomass comparison curves（ ABC curves） indicated that the current macrobenthic community in Banqiao Reservoir was stable. Combined with the biodiversity index,biological pollution index（ BPI）and Hilsenhoff biotic index（ BI）,it was suggested that Banqiao Reservoir suffered slight pollution.
