Shuitu Baochi Xuebao, 2006 选取农作区和荒草区两个不同利用模式下的红壤坡地，研究了降雨的入渗、产流及对土壤水分分布的影响。结果表明：（1）农作区和荒草区的径流系数都随着年限的延长而降低并达到稳定。降雨量成为影响径流量的唯一主导因素；农作区的径流系数显著高于荒草区（r〈0．05）。（2）农作区的入渗比率（入渗量／降雨量）低于荒草区；在持续降雨的情况下。农作区60cm以上土壤蓄水增量降低，但渗漏量保持不变．因此使入渗比率降低，而荒草区则在60cm以上土壤蓄水增量降低时，通过提高土壤的渗漏量保持较高的入渗比率。（3 ...

Shuitu Baochi Xuebao, 2008 针对我国东北半干旱地区坡耕地的耕作层逐年变薄,结构坚硬、紧密的犁底层上移变厚,造成土壤透水、通气性极差,土壤径流、泥沙侵蚀严重,严重影响水分的入渗。利用同心环有压入渗试验及野外模拟降雨试验,研究了在垄作区田的坡耕地中,根据区田土垱之间打破犁底层范围的不同,来分析坡耕地的犁底层对水分入渗的影响。结果表明局部打破犁底层后水分稳定入渗率提高,产流时间延长,径流和泥沙明显减少。

Shuitu Baochi Xuebao, 2003 滴灌入渗结束时的水盐特征是覆膜滴灌蒸发的初始条件,近年来覆膜种植技术的大面积推广使研究覆膜灌溉的水盐特征很有必要。通过非充分供水条件下滴灌入渗的三维水盐运移实验,分析了湿润锋运移的函数特征和椭圆方程,并对径向含水率剖面进行了研究。基于水分特征,分析了入渗中径向含盐率、径向浓度和径向Na 浓度剖面,并做出了相应水盐特征的等值线图。
