摘要
水溶性污染物和有机污染物在非饱和带的运动规律是当前土壤物理学研究的前沿领域．模拟反应性溶质的运移模型，必须包含溶质和土壤基质之间的保持和释放反应．本文简要综述土壤对溶质保持反应的平衡模型、动力学模型和多反应模型的主要特点．
Transport of soluble and organic pollutants in unsaturated soil is the advanced field of soil physics. To model foe transport of reactive solute effectively, the retention and release reaction models must ie specified. This article gives a brief summary of retention model of reactive solute in soil system, equilibrium model, kinetic model and multi-reaction models.
