摘要

用注水(双环)法和人工降雨法对陕西省淳化县泥河沟流域和安塞县纸坊沟流域坡耕地土壤水分入渗性能进行了研究。结果表明

用注水法试验所得土壤稳渗速率大于人工降雨法所得土壤稳渗速率

注水法仅能反映土壤本身的入渗特性

人工降雨法可以较好的模拟天然降雨入渗特性

2种方法所测定的土壤稳渗速率之间呈线性函数关系。

Abstract

The infiltration properties of slope farmland are studied by means of the water storage method and the simulated rainfall method respectively. The results show that the measured soil steady infiltration rates measured by the water storage method are greater than those measured by simulated rainfall. Using the water storage method may only reflect infiltration properties of soil itself

but the simulated rainfall method may simulate better natural rainfall. The steady infiltration rates measured by using two methods are a better linear relationship.
