在分析和总结国内外有关一维积水入渗条件下土壤水盐运移规律研究成果的基础上 ,针对盐碱土水盐运动的基本特征 ,通过室内一维土壤水盐运移过程的试验研究 ,分析了土壤盐分浓度分布规律 ,为盐碱地的开发利用提供了科学依据 Based on the research results of soil water and salt transport under the condition of one-dimensional water infiltration in China and other countries, the basic characteristics of water and salt movement in saline-alkali soil were studied through the experimental research on the process of water and salt transport in one-dimensional soil , Analysis of the distribution of soil salt concentration rules for the development and utilization of saline alkali provides a scientific basis
