摘　　要：采用BI指数法对辽河全流域24个点位进行水质评价,探讨辽河流域底栖大型无脊椎动物的群落结构及水质状况。结果表明,区域内共监测到底栖大型无脊椎动物134种,隶属于3门7纲17目36科93属,其中以水生昆虫为主,其次为环节动物、软体动物和甲壳动物。辽河水质评价结果与理化监测结果基本一致。BI指数在2.57~9.27区间内,水质评价结果为清洁的点位有6个,评价结果为良好的点位有9个,评价结果为轻污染、中污染和重污染的点位均为3个。The community structure and water quality of benthic macroinvertebrates in liaohe river basin were evaluated by BI index method.The results showed that a total of 134 species of benthic macroinvertebrates,belonging to 93 genera,36 families,17 orders,7 classes,3 phylums,were monitored in the region,Aquatic insects were the main species,followed by annelids,mollusks and crustaceans.The evaluation results of water quality in liao River Basin were basically consistent with the physical and chemical monitoring results.BI index was in the range of 2.57-9.27,there were 6 clean spots,9 good spots,3 light spots,3 medium spots and 3 heavy spots.
