摘要
以栅格植被根系层深度、田间持水量、饱和土壤含水量作为衡量流域内各点蓄水容量和最大蓄水容量的基础,建立了基于蓄满产流的栅格型分布式流域水文模型,并模拟了积雪融雪、蒸散发及产汇流过程。模拟结果表明,构建的流域水文模型模拟精度较高,方法可行。
A grid-based distributed watershed hydrological model is established to simulate the hydrological process in cold and arid regions with multi-source data. The mechanism of saturation excess runoff is considered in the model. The storage capacity and it＇s maximum of each and every points in a river basin are calulated by the land cover and soil type parameters of the vegetation root depth, field capacity and the saturated soil moisure.
