摘　　要：青海处在青藏高原生态脆弱地区,水电工程建设对河流区段生态因子,如地质、水文气候、生物、人文地理环境等产生影响。黄河干流已建、在建和规划建设的水电站共31座,总装机1970.35万KW,比理论蕴藏值扩大304.35万KW。从河流水能蕴藏量、电站规模、河流原生态的优劣区别、流域区系和生态承受力、开发区段局部影响力等方面分析,青海部分河流水电建设的密集度排序为:隆务河>大通河>黑河>湟水河>格尔木河>黄河;对河流生态影响的综合程度评价排序为:隆务河>大通河>黄河>湟水河>黑河>格尔木河。依青海部分河流的水电密集开发建设现状,分析评价由此对河流区段局部生态造成的影响程度,并提出对策。In fragile area of Qinghai-Tibet Plateau organism＇s habits , water and electricity engineering construction , to river the section organism＇s habits factor affects Qinghai if geology, hydrology, the climate ,living things , humanity geographic conditions etc. Come into being. Yellow River have been built, in construction planning and construction of a total of 31 hydropower stations with a total installed capacity of 19 703 500 kW more than the theoretical value of the potential expansion of 3 043 500 kW. From river water reserves, power plants the size , of the original ecology of the river pros and distinction, watershed flora and ecological tolerance, the development zone above the areas of local influence analysis, Qinghai part of the river hydropower construction - intensive to sort as follows ： Longwu River 〉 Datong River 〉 Hei River 〉 Huangshui River 〉 Gohnud River 〉 Yellow River; ecological impact of river comprehensive evaluation of the extent to sort as follows： Longwu River 〉 Datong River 〉 Yellow River 〉 Huangshui River 〉 Hei River 〉 Golmud River. According to the Qinghai - intensive part of the river hydropower development and construction of the status quo, analysis and evaluation of this section of the river local ecological impacts of the extent and come up with strategies.
