摘　　要：土壤疏水性是指水分不能或很难湿润土壤颗粒表面的物理现象。土壤疏水性研究不仅有助于合理评价疏水性对生态环境的影响,而且能为当前水土流失问题的解决提供新思路。本文对国内外土壤疏水性研究现状进行总结,着重阐述了土壤疏水性及产生机理、影响因素、测定方法及水文效应,并结合存在问题展望未来的研究,以期为我国开展相关研究提供参考。Soil water repellency is the hydrophobic property of soil which indicates the physical phenomenon that the surface of soil particles can not or hard to be moistened by soil water. Study on soil water repellency is not only helpful to assessing the impact of hydrophobic property of soils on ecological environment but also beneficial to providing soil erosion control with new approaches. The paper summarized the latest status on the researches in soil water repellency at home and abroad, mainly introduced the soil water repellency, mechanisms, determining methods and hydrological effect, and direction for the soil water repellency were advanced based on the existing problem. Then the strategies and suggestions were put forward in the end in order to research in China.
