Evolution and Prospects in Modeling of Water and Salt Transport in Soils

回顾了国内外土壤水盐运移模型的发展历程,根据土壤水盐运移模型构成的原理和发展趋势,将土壤水盐运移模型分为水盐平衡模型、物理模型和系统模型。借助国内外文献对已有模型的原理和应用进行了介绍,并对存在的问题进行了分析;展望了新形势下土壤水盐运移模型的未来发展趋势和研究重点,旨在为今后土壤水盐运移模型研究提供新的思路。

The mechanism of soil water and salt movement research is one of the core issues in soil salinization research. The study of modeling in soil water-salt transport is of great significance for find out the soil water and salt movement law. This article reviews the achievements of soil water-salt transport model, divided the soil water-salt transport model into water-salt balance models, physical models and system models in accordance with the principles and trends of water-salt transport in different soils. Introduced the theories and applications of existing models by means of literature at domestic and foreign, then analyzed the problems of existing models and prospected the future trends of soil water-salt transport model in the new situation and priorities for future research. Integrated modelling of soil water-salt transport, field and regional scalemodel for simulating soil water-salt transport, and water-salt transport model coupled with crop growth model are considered to be the key point of the research on water-salt transport model in the future. This article aims to provide new ideas for the study of soil water-salt transport model in the future.
