Abstract : digital basinis made from digital elevation model considering spatial variability within a catchment. on the basis of digital basin, the digital approach to describing hydrological processes within a catchment is investigated. digital hydrological model is regarded as a modern physically - based modeling technique that includes a large amount of information. the case study on the shiguanhe catchment in the huaihe river basin, intensified observation field of gewex asian monsoon experiment project, has shown that the digital mode lperforms very well not only in simulating runoff processes at any specific site, but also in simulating spatial distribution and temporal variation of hydrological elements and state variable ( especially soil moisture ), if compared with traditional hydrological models. that provides solid foundation for full use of now available observation in formation and in - depth mining of hydrological data
文摘:考慮流域下墊面空間變異性，基於數字高程模型構建了數字流域，並在此基礎上對描述流域水文物理過程的數字方法進行了探討.文章認為，數字水文模型是一種有物理基礎的包含大容量信息的現代模擬技術.史灌河流域實例研究表明，數字水文模型可以十分方便地輸出水文要素和狀態變量的空間分佈與時間序列，這對充分利用現有觀測信息進行水文信息的深層挖掘創造了條件 -

As to the hydrological characteristics of the basin, the last conclusion comes from that no matter which catchment, tao or tangnihai basin, there are significant differences in rainfall and runoff between upstream and downsteam. for tao river basin, the key runoff area located at mianxian and upward region, and maque and upwards for tangnihai basin
（ 9 ）挑河流域和唐乃亥流域內不論是降水還是下墊面條件，上下游都存在著明顯的差異，這種差異在挑河流域以崛縣站為分界，確定崛縣站以上流域是挑河的主要產流區;在唐乃亥流域以瑪曲站為分界，確定瑪曲站以上流域是唐乃亥的主要產流區。
