岷江上游水电开发对河道减脱水的影响研究
Impact of hydropower development in upper reaches of Minjiang River on flow reducing of river reaches
摘要
Abstract
Based on the field investigation of hydropower stations in the upper reaches of the Minjiang river and the affected reaches, we established a evaluation indicator system of the flow reducing reaches( or dried reaches) , and analyzed the flow re-ducing( or dried) conditions of the mainstream, first tributary and second tributary of the river. According to analysis results, we discussed the relationship of the flow reducing ( or dried) condition and the distance from the investigation section to the dam site, power station type, installation capacity and adjustment ability. The results show that the flow reducing reaches ( or dried reaches) caused by the hydropower development is very serious in this region;discontinuous flow phenomenon of different degrees appear at all levels of the upstream tributaries, especially in the secondary tributary;and the reducing reaches ( or dried reaches) is less serious as the distance from the dam site increases;the type and regulation performance of power stations are obviously re-lated with the flow reducing reach ( or dried reach) , but the installed capacity has no influences. So it is necessary to take ac-count of the impacts of power station's type and regulation performance when formulating a basin hydropower development and riv-er ecological recovery plan.关键词
