| 摘 要： | 近些年,由于气候变化和人类活动的双重作用改变了流域下垫面的水文特性,探讨研究下垫面变化的水文响应过程具有重要的理论和现实意义.河南伊河洪水虽然量级不大,但发生几率较高,对水库运用和河道冲淤的影响较大.如果洪水变小,伊河下游的造床流量也相应减小,水库控制中常洪水的流量及所需的防洪库容可做相应调整,反之亦然.因此,为了科学...

| Abstract: | In recent years,climate change and human activities have changed the hydrological characteristics of underlying surface.In this condition,it is of important theoretical and practical significance to study how the flood responds to the changes of land utility and cover.The flood level of Yi River,Henan Province is not high but it occurred with high frequency and has a negative effect on the reservoir and channel.If the flood volume turns small,the downstream flow of Yi River can also become small.Reservoir c... |
