土壤污染物溶质运移模型研究进展

土壤中污染物溶质的运移已经成为了近年来研究的热点。本文回顾了关于土壤中溶质运移模型的研究成果,讨论了各个模型的优势及其不足之处,介绍了应用最为广泛的传统微分方程模型。对应用于非均匀介质中的随机运移模型进行了描述,并将其和传统微分方程模型进行了比较。介绍了可动-不可动水体模型并讨论了其相关参数的影响因素。列举了几种和其他学科或研究方向结合的溶质运移模型。最后提出了今后模型开发的发展方向。

Research Development of Polluted Solute Transport Model in Soil

The transportation of polluted solute has become the focus of research these years.This paper reviews the research result of modeling solute transport in soil and discusses the advantage and disadvantage of these models.The traditional differential equation model,which is most extensively used,is introduced.The stochastic transport model that used in heterogeneous media is described and compared with the traditional differential equation model.And several solute transport models that combined with other subjects or fields are enumerated.In the end,the developmental direction of model developed is indicated for the future.
