在世界干旱和半干旱地区分布着大面积的盐渍土,在原来没有盐渍化的地区,由于管理不当,引起土壤次生盐渍化,严重影响农业的发展。土壤盐渍化的防治问题已成为农业生产中的重要问题。盐渍土研究中一个重要方面是盐渍土水盐动态的研究,也称为水盐运动规律的研究,它是研究盐渍土发生演变和防治措施的基础。早年盐渍土研究就已注意水盐动态研 In arid and semi-arid areas of the world, a large area of ​​saline soil is distributed. In areas where there was no salinization, secondary salinization of soil is caused due to improper management, which seriously affects the development of agriculture. Prevention and control of soil salinization has become an important issue in agricultural production. An important aspect in the study of saline soils is the study of the dynamics of salt and water in saline soils, also known as the study of the movement of water and salt, which is the basis for studying the evolution and control measures of saline soils. Early saline soil study has been concerned about the dynamic study of water and salt
