摘要
参照降雨、径流响应函数模型，建立流域降雨、输沙响应函数模型，用模型的输入（降雨）及输出（输沙）过程的实测资料和最小二乘法推求模型的响应函数ｈｓ。ｈｓ确定后，只要已知流域的降雨过程，便可通过矩阵计算，推求出流域出口断面的输沙率过程。本模型在李子溪流域及嘉陵江区其它小流域作了实际应用与检验。得到了满意的结果。
A precipitation～sediment transport response function model has been presented aswhich is derived by taking reference to the precipitation ～runoff re-sponse function model.Based on the observed precipitation data (medel input)and sediment data(model output),hs is conducted with the least square method applie, once hs is determined,withthe rainfall process given,the sediment transport process at the outlet cross-section of the basincan be obtained through matrix calculation as. This model has given satisfactoryresults with applied and evaluated in Lizixi Basin and other basins.
