摘    要:简述了土壤斥水的基本概念,归纳了土壤斥水对农田水分循环、水土保持、地下水环境等的影响,分析了土壤斥水发生的原因,总结了国内外已采用的斥水度测定方法及其各自特点,并对土壤斥水度空间变异性、斥水土壤在入渗和蒸发过程中的水分运动规律及斥水土壤入渗性能改善方法的研究现状作了较全面的分析和评述。由于土壤斥水与农田水分循环、微生物活动、产流产沙和地下水环境污染之间存在密切联系,因此有必要进行相关问题的研究。

关 键 词:土壤斥水性  滴水渗透时间法  空间变异性

Abstract:The basic concept of soil water repellency was introduced, the effects of soil water repellency on field water cycle, soil and water conservation, and groundwater environment was summed up. The reasons of soil water repellency were analyzed. The domestic and international methods used for detecting the degree of soil water repellency and their characteristics were introduced. The research advancement of spatial variability for soil water repellency, soil water movement of water repellent soil during infiltration and evaporation process, and measures for improving infiltration ability of hydrophobic soil were also reviewed and assessed thoroughly. Since there were closed associations between soil water repellency and filed water cycle, microbe activity, runoff and sediment production, and pollution of ground water environment, it was urgent to do related research.
Keywords:Soil water repellency  Water drop penetration time  Spatial variability
