【摘要】 为了更好的了解和保护黄河炳灵水电站库区的鱼类资源及其生态环境,在2008～2009年,对黄河炳灵水电站库区的浮游生物和鱼类资源进行了调查。浮游生物调查结果显示,该库区共有浮游植物2门9种属,生物量为0.7982 mg·L-1,以硅藻门为优势种类;浮游动物4类10种,生物量为0.0164 mg·L-1,以原生动物为优势种类。鱼类调查的结果显示,黄河炳灵水电站库区分布有鱼类有12种,其中鲤形目10种,鲶形目1种。优势种类为黄河裸裂尻鱼、似鲶高原鳅、黄河鮈及兰州鲶。与1981年刘家峡水库的浮游生物和鱼类资源调查结果相比,浮游生物平均生物量下降,鱼类种类组成有所减少,部分鱼类已灭绝或濒临灭绝,且鱼类处于严重低龄化。更多还原

【Abstract】 In order to find and protect the ecological environment and fish resources in Bingling Reservior of Yellow River scientifically,investigations on plankton and fish resources had been carried in 2008-2009.9 species(genera) and 2 phylum of phytoplankton,4 species(genera) and 10 phylum of zooplankton,12 species(genera) of fish had been found,which shows that the general trend of plankton is that the average biomass is getting apparently decreased.Sp-Pylzovi Kessler,T(T-) siluroides(Herz),Silurus lanzhouensis Chen,Carassins auratus Linnaeus,Gobio huanghensis and Abbottina rivularis are the majority species in the fishing games,which shows that these resource restore somewhat,but We didn’t find any T.(T.)rapplnheimi(Fang),Lenciscus walechkii(Dybowski),Squaliobarbus curriculus(Richardson), Acanthogobius guentheri Herg,Hemiculter leucisculus(Basil) and Platypharodon extremus Herz.Fish gradually miniaturization in Bingling reservior of Yellow River River has been noticed.更多还原
