| 摘 要： | 本文根据室内土壤物理实验研究结果和理论推导,提出参数B同流域土壤含水量建立关系的入渗模式。该模式不仅能够反映可变初始土壤含水量对入渗的影响,而且能够进行饱和与非饱和入渗的连续过程计算。当用于以开始积水时间t_p,为判别标志的产流计算模型中,采用小流域、径流实验场的水文资料和室内土柱入渗的实验资料进行模拟计算,结果良好。

| Abstract: | Based on the experiment results of soil physics in laboratory and theoretical analysis, the paper derives a infiltration formula through a relationship between parameter B and soil moisture in watershed. The formula can reflect the affect of variance of initial soil moisture and evaluate the continuous process of saturated and unsaturated. Regarding the appear of ponding time tp as a judge mark, a model, combining with the formula, is developed. The hydrologic data of small watershed and runoff experiment filed, the experiment data of soil column infiltration in laboratory are used in the model to simulate the excess rainfall, the result is better. |
