土壤重金属迁移模拟研究的现状与展望

随着工业发展和废弃物的排放不断增加，土壤重金属污染已经成为一个世界性环境问题。土壤重金属的分布转化以及污染修复的研究受到广泛关注，数学模型及计算机模拟研究成为重要的研究手段。该文对土壤重金属迁移的模拟研究的进展进行了回顾与归纳，集中阐述了对流弥散和经验随机两大类模型的特点和应用，并指出了研究中存在的问题及今后研究的发展方向。将数学模拟与土壤重金属信息系统及地理信息系统GIS的有机结合，将有可能为环境保护和农业决策提供新的重要依据。

Modeling heavy metal movement in soil: review and further study directions

With the development of industries and their discharges of pollutants, soil contamination by heavy metals has become increasingly the world wide environmental problem. It has been a hot topic to study the distribution, transformation and fates of heavy metals in soils and the remediation of contaminated soils, with mathematic models and computer simulation as research tools. This paper reviews the progresses in the researches on modeling the heavy metal movement in soils. The discussion is focused on the characteristics and applications of Convection-Dispersion models and stochastic empirical models, including the limitations and the further study directions of the models. Combining the modeling of heavy metals in soils with MIS or GIS is of significance in future research, to supply a useful tool for environmental protection and agricultural management decision-making on heavy metal pollutants management.
