| 摘 要： | 在水文水资源分析计算中，对降雨损失的处理，往往只对蒸散发和土壤下渗量进行计算，忽视了植被的降雨截留损失，这样至少说在理论上是不完善的。因而，在水文分析计算中，准确模拟植被的降雨截留过程，对合理评价水资源量，具有现实意义和理论价值。在系统分析复合生态系统的降雨截留过程的基础上，建立了半理论的复合生态系统截留计算模型，用于小型生态流域模拟降雨截留过程，不仅丰富了水文学的内容，而且完善了降雨损失计算的理论。

| Abstract: | In analysis and computation of hydrologic data and water resources,only rainfall evaporation and rainfall infiltration in soil are often taken into account for rainfall losses,with rainfall interception by vegetation neglected,which is at least imperfect in theory.Therefore,in hydrologic analysis and computation,accurate simulation of the process of rainfall interception by vegetation is of practical significance and theoretical value to reasonable assessment of water resources amount.Based on systematically analyzing the rainfall interception processes of compound ecological systems,a semi-theoretical computation model for the rainfall interception of compound ecological systems was developed to be used for modelling the rainfall interception of small ecological watersheds.The model not only enriches the contents of hydrology but also perfects the theory of rainfall losses computation. |
