土壤中水、热、盐耦合运移机理与模型的研究进展

Advance of Research on Theory and Model of Coupling Transportation of Water,Heat and Salt in Soil

土壤水、热、盐运移规律的研究是目前土壤学、农田灌溉、水土保持、环境科学等学科研究的一个热点问题,也是防治土壤次生盐碱化,提高土壤肥力和土壤生产效率的重点。为此,简要介绍了土壤水、热、盐运移基本理论的发展过程和国内外学者数十年来关于土壤水、热、盐的研究成果,并对土壤水、热、盐运移模型研究进行了一定的评价,讨论了目前该研究领域急需解决的问题,为进一步的研究提供帮助。

The research on the coupling transportation of water, heat and salt is a hot topic for some subjects research, such as soil science, farmland irrigation, conservation of water and soil, environmental science. It is also key content of research on preventing and controlling secondary Salinization of soil, enhancing soil fertility and soil production efficiency. Therefore, this paper briefly introduced the developing process of basic theory of transportation of soil water, heat and salt in soil, and certain research achievements of the domestic and foreign scholars about this topic in past years. Then, certain appraisal was made on the model of transportation of water, heat and salt in soil. Moreover, the urgent issues that need to be solved in this territory were discussed to provide help for the further study.
