本文比较了三个实验流域的水文循环特性，并应用不同类型的集总参数模型来理解流域的水文循环。其中一个是森林集水区，另一个包括开垦的旱地，最后一个是梯田稻田。水文性质的比较表明，土地利用方式的差异对表层土壤性质有较大的影响，从而引起蒸散发和暴雨径流等水文过程的变化。通过径流分析模型，得到了流域径流量观测值与计算值的较好吻合，优化模型参数和水量收支分量值的差异反映了它们之间水文循环的差异。
In this paper, properties of hydrologic cycle in three experimental catchments were compared and different types of a lumped parametric model were applied to understand the hydrologic cycle in the catchments. One of them is a forest catchment and another one includes the reclained upland fields and last one does terraces paddy fields. The comparison of hydrologic properties showed that the differences in land used have great influences on the soil properties of surface layer, which cause changes in hydrologic processes such as evapotranspiration and storm runoff et.al. By the runoff analysis models, good agreements between observed and calculated discharge from the catchments were obtained and it was found that the differences in values of optimized model parameters and water budget components reflect those in the hydrologic cycle among them.
