【摘要】 土壤斥水性是指水分不能或很难湿润土壤颗粒表面的物理现象。土壤斥水性是一个全球性现象,可以出现在各种气候背景、土壤类型和植被覆盖条件下,并且影响到地表水文过程的诸多重要环节,因此受到广泛关注。有关土壤斥水性的研究是表面科学、生物学、土壤学以及物理学等学科交叉的前沿研究领域,已成为国际生态水文学研究的重要核心科学问题。复杂多变的时空分布特征,是目前量化其生态水文效应的困难所在。在综述国内外研究动态的基础上,简要回顾了该领域的发展历史;对土壤斥水性的发生机理、影响因子及其对水文过程的影响机理,进行了较为全面的总结和讨论,并指出了目前存在的问题和未来的研究重点,以期促进我国相关研究,为生产实践及科学决策提供借鉴依据。更多还原

【Abstract】 Soil water repellency is a worldwide phenomenon,which can occur under various climate background,soil condition and vegetation types.The eco-hydrological process can be significantly modified by the water repellent soils and has attracted much attention in the past decades.As a matter of fact,the study of this issue has already became the interdisciplinary subject of the surface science,biology,soil science and physics.The environmental potential of the water repellent soil is now one of the frontiers and perspectives of eco-hydrological research.Due to its complicated spatial and temporal properties,it is very difficult to quantify the ecohydrological effects of soil water repellency.Based on the recent achievements,the historical development of the issue was reviewed briefly.Meanwhile,its physical mechanism,influence factors as well as its potential effects on eco-hydrological processes were discussed.The main aims of the studies on this issue in the future were also pointed out.We hope this overview could promote the development of the study of soil water repellency and provide the scientific basis for government decision in China.更多还原
