小流域地表水资源动态模型研究

Study on dynamic state model of the earth's surface water resources in small watershed

通过在小流域中进行降雨径流定点观测,建立地表水资源动态模型,对模型中影响地表水资源变化的物性参数地形系数(T)、土壤系数(S)和覆盖系数(C)的计算方法和实验结果进行论述,同时在仁国小流域上进行了验证。结果表明,该模型能够对小流域地表水资源进行动态监测,从而使有限的水资源更好地为生产和生活服务。

Through carries on fixed point observation of rain and runoff in the small basin, put forward a dynamic state model of water resources in small watershed. A few physical parameters affect change of the earth＇s surface water resources in the model. They are terrain coefficient（T）, the soil coefficient（S） and the cover coefficient（C）. The article carried on discussion for the computational method and the experimental result. The model is verified by the observation data of the renguo small watershed. The result indicated that this model can carry on the dynamic monitor of the earth＇s surface water resources in the small basin. The limited water resources serve for the production and the life.
