| 摘 要： | 选择大清河水系的紫荆关流域为研究区,分析了其下垫面变化趋势,根据大清河水系的水文气象特点,建立了考虑下垫面变化的超渗-蓄满耦合产汇流模型,并利用实测暴雨洪水资料进行了参数率定和模型验证.利用该模型研究了流域洪水对下垫面变化的响应.结果表明:下垫面变化导致洪峰和洪量变小,其对大洪水影响小,对中小洪水影响较大.对于10年一...

| Abstract: | Flood peaks and volumes have decreased in Daqinghe River Basin in recent years.To search for the effects of underlying surface on flood decrease,Zijingguan watershed in Daqinghe River Basin was selected as a study area,and the statistical analysis of the underlying surface change was done,including land use change and soil moisture storage capacity variation.The remote sensing land use data of 1980 and 2000 were used,and the main change is forest increase,but grassland and arable land decrease.We selected s... |

| Keywords: | underlying surface land use soil moisture storage capacity hydrological model flood response |
