摘　　要：土壤溶质迁移的研究已成为土壤学、生态学、水资源学以及资源与环境科学等相关学科的基础和前沿研究领域。人们试图通过发展简单数学模型来描述土壤溶质迁移过程,以及影响溶质迁移特征因素间内在关系。通过对非饱和土壤水分与溶质迁移参数间的关系分析,探寻简单方法确定相关迁移参数。分析结果表明,参数估算是可行的,可以用该参数进行模型预测。The research on the soil solute transport has been a fundamental and cutting-edge field in soil and water sciences, ecology and other relevant disciplines in association with resources and environmental studies. People tried to develop a simple mathematical model to describe the soil solute transport process- es, and solute transport characteristics affected the intrinsic relationship between factors. Based on the relationship between unsaturated soil water and solute transport parameters, and explored a simple method to determine the parameters related to migration. The results showed that parameter estimation was feasible, and this parameter could be used to the model predictions.
