2014年10月对辽宁省境内的蒲河大型底栖无脊椎动物(以下简称底栖动物)群落结构进行了调查研究，共采集到底栖动物3门5纲12目22科39属44种。其中，节肢动物门35种，占总种类数的80%，环节动物门5种，占11%，软体动物门4种，占9%。优势种有小云多足摇蚊、溪流摇蚊、霍甫水丝蚓、负子蝽、划蝽、绿倒毛摇蚊、浅白雕翅摇蚊、苏氏尾鳃蚓。采用EPT百分比、BMWP-ASPT、Berger-Parker指数和BI指数对蒲河水质进行评价，结果表明，BI指数法结合指示生物法更适于蒲河流域水质生物评价，蒲河流域整体水质存在污染，且生物多样性遭到破坏，需要进行水生态修复与重建。

The community structure of macrozoobenthos was investigated in Pu River basin at October in 2014.A total of 44 species of macrozoobenthos were collected,belonging to 3 phyla,5 classes,12 orders,22 families and 39 genera.Among them,the Arthropoda included 35 species,accounting for 80%of the total species number.The Annelida included 5 species,accounting for 11%of the total species number.The Mollusca included 4 species,accounting for 9% of the total species number.The prevalent macrozoobenthos species were Polypedilumnubeculosum,Chironomusriparius,L.hoffmeistteri,Belostmatidae,Corixidae,M.chloris,Glyptotendrpespallers,Branchiurasowerbyi Beddard.The assessment of water quality was conducted by EPT,BMWP-ASPT,Berger-Parker Index and Biotic Index(BI),and the results showed that BI method combined with Bio Indicator method was more suitable for water quality evaluation of Pu River basin.The overall water quality of Pu River was polluted,and the biodiversity was damaged,so it’s need for water ecological restoration and reconstruction.
