| 摘 要： | 2009年7月对黄盖湖水系河源区--皤河的大型无脊椎动物进行调查。共采集到无脊椎动物54种，隶属于4门6纲36科。其中水生昆虫45种，软体动物4种，甲壳动物2种，寡毛类、涡虫纲、蛛形纲各1种。无脊椎动物密度方面的优势类群主要为蜉蝣目稚虫和摇蚊幼虫。宽基蜉(Choroterpes sp.)、微动蜉(Cinygmula sp.)、四节蜉(Baetis sp.)和无突摇蚊 (Ablabesmyia sp.)是最优势的种类，其相对丰度分别占总丰度的4040%、838%、426%和419%。典范对应分析（CCA）显示，海拔和河宽是影响无脊椎动物群落分布的关键环境因子。采用Shannon Wiener指数和BI生物指数对各样点的水质状况进行了评价：二者结果具有一定差异，BI指数的评价结果更符合实际情况

| Abstract: | During July of 2009,macroinvertebrate assemblages were investigated in Pohe Stream which is an important headwater system belonging to Huanggai Lake water-network,located in Chibi County,Hubei Province.A total of 54 taxa were identified,belonging to 4 phyla,6 classes and 36 families.Of which 45 were aquatic insects,4 mollusks,2 crustaceans and 3 others(oligochaete,turbellarian and arachnidan).The larvae of Ephemeroptera and Chironomidae were the dominant groups in abundance.Choroterpes sp.,Cinygmula sp.,Bae... |
