摘　　要：2009年4月中、下旬对岷江支流越溪河底栖动物群落结构进行了调查,并应用生物指数对河水水质进行了综合评估.结果表明:越溪河春季共采集到底栖动物46种,其中节肢动物22种,软体动物19种,环节动物4种,扁形动物1种.不同微生境底栖动物种类组成、平均生物量和各类群平均密度差异较大,体现了植被较丰富、工业相对不发达而水电开发较早的丘陵地区河流底栖无脊椎动物群落结构的典型特征.生物指数评价结果显示小井沟河段水质清洁,符合饮用水标准.Community structure of macrozoobenthos and the bioassessment of water quality in the Yuexi Stream＇a tributary of the Minjiang River＇were investigated in middle April,2009.And a cormprehensive assessment was made of the water quality of the river through biotic indices.The results showed that,among the altogether 46 species of macroinvertebrates collected in the river,there were 22 species of Anthropoda,19 species of Malacostraca,4 species of Annelida,and one species of Latyhelminthes.Dramatic difference is observed of the zoobenthos in their species composition,average biomass and average density,which is typical of the community structure in those rolling countries having a rather abundant vegetation yet with an underdeveloped industry and an advanced hydroelectric development.The results from the bioassessment of water quality show thsat water in Xiaojinggou reach is clean and meets the dringking water standard.
