摘　　要：本文以淮河上游的竹竿河流域为研究区，应用SWAT模型对竹竿河流域的径流、泥沙及面源污染负荷的产输出过程进行模拟计算。利用竹竿铺站1996年的实测月径流和泥沙数据进行模型的调参计算，用1998年的实测月径流和泥沙数据以及1991-2000年径流和泥沙数据对模型进行验证，并利用竹竿铺站2004年6月3日～14日的实测水质数据对模型的面源污染相关参数进行确定，验证结果表明模型基本合理可行，可用于竹竿河流域面源污染的模拟计算。根据模拟结果对该流域的径流、泥沙和面源污染负荷的时空产输出特点进行了分析，为流域面源污染控制防治规划提供科学依据。Zhuganhe watershed in the upstream of Huaihe river basin is selected as the study area. SWAT model is applied to simulate the producing and transporting process of flow, sediment and non-point source pollution. Monthly flow and sediment data series of 1996 are used to calibrate the correlative parameters of flow and sediment. The monthly flow and sediment data series of 1998 and yearly data series of 1991-2000 are used to validate model. Water quality data of one-storm event of June 2004 are used to calibrate the correlative parameters of non-point source pollution. The results of calibration and validation show that the model is reasonable and available. Based on the simulated results, the spatial and temporal distribution of flow, sediment and non-point source pollution has been analyzed for the non-point source pollution control.
