| 摘 要： | 以桥沟小流域为研究对象,利用该流域不同地貌部位的野外径流场及沟道水文站网观测资料,计算了不同场次降水的泥沙输移比,较为系统地研究了影响桥沟流域次降水泥沙输移比的水文要素。结果表明:土壤前期含水量、流域的降水过程特征、洪峰流量、径流量、水流含沙量是影响次降水泥沙输移比的主要水文要素;提出了表示降水、径流、泥沙对泥沙输移比影响的表征参数,即降水峰现系数、径流侵蚀力和泥沙相对容重。

| Abstract: | Taking Qiaogou watershed as a study area,the sediment delivery ratio under single rainfall events was calculated based on the data from field runoff plots built at different topographic position and hydrological station.And the relationship between sediment delivery ratio and hydrological elements was systematically analyzed.The results showed that the antecedent soil moisture,characteristics of rainfall course,the peak flow,runoff discharge and the sediment content are the dominant hydrological factors inf... |
