摘　　要：本研究以珠江水系南盘江一级支流马别河为研究对象,根据野外调查结果对马岭水利枢纽工程坝址上下游河段的生境特征与鱼类资源组成进行系统剖析。研究发现,马岭水利枢纽工程影响河段为典型的高山峡谷河段,水文水温变动规律明显,饵料生物资源主要以着生性藻类和底栖动物为主。工程影响河段共采集到22种鱼类,以喜流水性鱼类为主。坝上河段的优势物种为三齿华缨鱼、唇■、南方白甲鱼、云南光唇鱼,而坝下河段的优势物种为唇■、云南光唇鱼。相比之下,坝上河段的Maegalef丰富度指数和Simpson指数略大于坝下河段。In the present study,the habitat characteristics and fish community structure of the upstream and downstream of the Maling dam in the Mabiehe River,a first tributary of the Nanpanjiang River in the Pearl River system,were systematically analyzed based on field investigation.It found that the assessed object was a typical high mountain and canyon river reach,with obvious hydrological and water temperature changes,and the biota resources were mainly periphytic algae and benthic animals.A total of 22 fish species were collected in the assessed river reach,which mainly consisted of rheophilic fishes.Hemibarbus labeo,Hemicculter leuciclus,and Acrossocheilus yunnanensis were the dominant species in the upstream of Maling dam,while Sinocrosscheilus tridentis,H.labeo,Onychostoma gerlachi,and A.yunnanensis were the dominant species in the downstream of Maling dam.In contrast,the Maegalef richness index and Simpson index of the upstream were slightly larger than those of the downstream.
