摘　　要：以淮河上游大坡岭水文站以上为研究流域，将新安江模型与修正通用土壤流失方程耦合，构建基于网格尺度的流域坡面泥沙负荷计算模型，结合河道泥沙输移计算模型，实现流域径流量、泥沙负荷时空变化全过程模拟。应用2000-2008年实测日降水、日蒸发、日流量和日含沙量等资料，以日为时间尺度模拟计算了大坡岭站的径流量和泥沙负荷。结果表明，新安江模型可成功应用于淮河流域水土流失预报，扩展了新安江模型的应用领域，对从源头控制淮河流域上游水土流失和面源污染、水土资源的可持续开发和利用具有一定的指导意义和参考价值。This paper selects the subbasin located above Dapo[ing Hydrologic Station in upper reaches of the Huaihe River Basin as the case study site. Coupling the Xin＇anjiang Hydrologic Model with modified universal soil loss equation, basin slope sediment load model is established by grid scale together with channel sediment transport model. The spatial temporal variations of runoff and sediment load simulation are carried out. Based on the daily data of precipitation, evapotranspiration, discharge and sediment concentration during 2000 to 2008 year, the runoff and sediment load of Dapoling Hydrologic Station are computed with daily time scale. The result reveals that the Xin＇anjiang Hydrologic Model can be applied in upper reaches of the Huaihe River to predict the water and soil losses, which extends the application area of the Xin＇anjiang Hydrologic Model. Research output of this paper provides a valuable reference for the future water and soil losses and non-point poilu＊ion controlled from the source and the sustainable development and utilization of water and soil resources in Huaihe River Basin.
