摘 要:为了保护黄河鱼类资源及其生态环境,从2002年开始,先后9次对黄河干流中、上游河段,依据《内陆水域渔业资源调查手册》,采用实地捕捞、走访了解等方法进行水生生物的调查研究。调查结果为浮游植物8门、87种属,浮游动物6门、42种,底栖生物14种属,水生植物5种,鱼类38种。用本次调查结果与1982年黄河水系渔业资源调查对比分析,结果表明,黄河中上游浮游生物表现出明显的变化,总的趋势是平均生物量下降;黄河干流中上游河段土著鱼类濒危加剧,鱼类逐渐小型化,存在着一定的水生生物入侵问题;建议开展黄河水系水生生物资源的系统调查,制定黄河渔业资源保护规划,这项工作是修复黄河水域生态环境,维持生物多样性的重要基础,对于黄河流域人民生存、生活以及经济可持续发展有着十分重要的意义。In order to protect scientifically the fishery resources and eco-environment of Yellow River , nine investigatioins on hydrobios in the middle and upper reaches of main Yellow River had been carried out since 2002 according to The Standard for the investigation of inland fishery resources. The investigations showed the present status of the fishery resources in these reaches are as follows :87species (genera)and 8 phylum of phytoplankton,42 species and 6 phylum of zooplankton, 14 species(genera) of banthic organism , 5 species of hydroplant, 38 species of fish. A comparative analysis,With the results of "the Yellow River Fishery Resources Survey in 1982",shows that the general trend of the plankton is that the average biomass is getting apparently decreased, the aboriginal fishes are endangered intensifically, and there must be some problem of aquatic biological invasion in these reaches. A granual miniaturization of fishes in main Yellow River has been noticed. The authors proposed to carry out investigation and researches on hydrobios resources in main Yellow River , and develop plans to protect the fishery resources in yellow River, which will be an important basis for rehabilitation of the Yellow River waters and it's ecological environment, for the maintenance of biological diversity of Yellow River's waters. And this work will be of great significance for people's life and sustainable development of economics in Yellow River basin.
