Shuitu Baochi Xuebao, 2008 通过微咸水入渗实验结果和入渗模型分析实验资料方法研究了碱土、盐土在微咸水入渗条件下土壤水盐运移特性。结果表明:当矿化度在一定范围,相同入渗时间内两种土壤的累积入渗量、湿润锋随入渗水矿化度的增加而增加;不同SAR的微咸水入渗对盐土、碱土入渗能力影响不大,特别是盐土。碱土的水分和盐分运移与入渗水矿化度均呈正相关关系,盐土则不然。

Shuitu Baochi Xuebao, 2008 针对西北等干旱地区土地次生盐渍化的问题,以室内试验为基础,测定盐碱土在不同滴灌施钙浓度下水盐运动过程,研究了不同施钙浓度对盐碱土土壤盐分运移和水分运动的影响。结果表明,不同施钙浓度的湿润锋水平、垂直最大运移距离与钙离子浓度之间均符合线性关系,湿润锋的水平、垂直运移距离与入渗时间之间符合幂函数关系,随着湿润锋水平、垂直湿润距离的增加,不同滴灌施钙浓度的土壤含盐量、钠离子含量均在不断增加,随着施钙浓度的增加,脱钠区深度系数增大,脱盐效果明显。

Shuitu Baochi Xuebao, 2020 为分析透气隔水（弱透水）埋体促进水分入渗与溶质运移功效，开展了不同容重（1.40，1.45，1.50，1.60 g/cm3）透气隔水（弱透水）埋体的一维垂直土柱入渗试验，分析了不同容重的透气隔水（弱透水）埋体对土壤水分入渗与溶质分布的影响。结果表明，透气隔水（弱透水）埋体能够增加土壤累积入渗量，推动湿润锋运移，在一定范围内，随着透气隔水（弱透水）埋体容重增加，湿润锋推进速度与土壤入渗率均增加。600 min时，土壤累积入渗量相对增加7.42%~29.17%，湿润锋深度达到27 cm，入渗时间相对减少26.
