摘　　要：文章以数字高程模型(DEM)和地理信息系统(GIS)为基本支撑,将尼尔基流域划分为12个子流域,基于子流域构建分散式融雪径流模型,通过模拟各个子流域出口的融雪径流,并结合各子流域之间的空间拓扑关系和汇流计算,实现尼尔基水库的融雪径流预报。应用结果表明,该模型在一定程度上达到了模拟预报尼尔基水库入库水量的目的。Based on the DEM and GIS, the paper divides Nierji reservoir basin into 12 sub-basins, establishes distributed snowmelt runoff model for each sub-basin and then simulates snowmelt runoff of each sub-basin outlet, realizes snowmelt runoff forecasting combining topological relation with flow concentration calculation of each sub-basin. The results show that the model could simulate and forecast the inflow of Nierji reservoir to some extent and provide decision supports for the snowmelt runoff forecasting, the water resources management and the flood control scheduling for the Nierji reservoir.
