| 摘 要： | 传统水文模型在水量模拟实践中取得了一些满意的结果,但由于传统水文模型大多不能反映下垫面特性对降雨径流过程的影响,从而限制了其在更广泛涉水领域的应用和发展.本文在地貌形成理论的基础上,充分考虑了流域内地形、植被、土壤、土壤水分参数等因素对流域蓄水容量空间分布的影响,提出了基于栅格蓄水容量空间变异的分布式水文模型.

| Abstract: | Traditional hydrological models were robust in water quantity simulation. However,these models were very weak in calculating the impact of the underlying surface on the rainfall-runoff process,and this drawback limited the application and development of traditional models. On the basis of geomorphic process theory,it took into account several hydrological related factors such as watershed terrain,vegetation cover,soil type and soil moisture parameters,meanwhile these factors’ impact on the spatial distribution of watershed water storage capacity. It brought out a spatial distributed model of water storage capacity,and integrated it with the saturation excess runoff mechanism and the vertically-mixed runoff mechanism into watershed hydrologic models based on the spatial distributed model of water storage capacity. This model structure was reasonable relatively,and was used to the study process simulation,discipline of evapotranspiration pattern,and watershed drought assessment and classification. |
