摘　　要：建立了高山深谷地区基于物理机制的流域分布式模型.模型描述了坡面流和壤中流沿坡向的变化,从而可以反映出高山深谷地形上的长坡面和陡坡面水文信息沿坡向或垂向变化.模型初步应用于拉萨河流域,对1999和2000年汛期的产汇流过程进行了并行计算,模拟效果良好,初步验证了模型的合理性和适用性.A physically based, distributed, hydrological model for high-relief mountainous regions is presented. This model characterizes the spatial variation of the surface and subsurface flows within a slope unit, accounting for the effects of hydrological information nonuniformity along the long and steep slopes. The model is applied to the Lhasa River basin, Tibet, China, for simulating the rainfall-runoff process in the raining season of 1999 and 2000. The simulation results are in reasonable agreement with the observed data, exhibiting its applicability to high-relief mountainous regions.
