摘　　要：冠层截留现象作为降水再分配的首个环节,通过对降水的拦截改变到达地面的降水总量及空间分布,对于流域水文过程和生态过程均具有非常重要的意义。通过综述冠层截留主要的研究方法和计算模型,深入剖析降水在冠层中运动的微观物理过程,如雨滴在叶片上的附着、弹跳、飞溅等现象的机理规律,探讨现有冠层截留计算方法存在的问题和未来的研究展望。As the first link of precipitation redistribution,the interception of canopy interception changes the total amount and spa⁃tial distribution of precipitation reaching the ground,which is of great significance to the hydrological process and ecological pro⁃cess of the basin.This review expounds the significance of the canopy interception,canopy intercept main research methods and calculation model,and deeply analyzes the precipitation in the canopy movement of the microscopic physical process of the rain on the blade attachment,bounce,splash phenomenon mechanism rule,discusses the existing problems of canopy interception calcu⁃lation method and the future research.
