截留是降水被植被冠层截留并重新分配到地面、大气或植物中的过程。截留损失是指通过植物表面蒸发返回大气或被植物吸收的那部分降水。因此，它是一个地区实际发生的降水量与到达地面的降水量之间的差异。Horton [1919]第一次对拦截过程进行了全面的讨论，并总结了他自己收集的数据以及其他人发表的数据。他指出，拦截损失是（1）风暴结束时储存在植物表面（随后通过蒸发返回大气层）和（2）风暴期间潮湿植物表面蒸发的总和。
Interception is the process in which precipitation is caught by a vegetative canopy and redistributed to the ground, to the atmosphere, or into the plant. Interception loss is that portion of the precipitation which is returned to the atmosphere through evaporation from plant surfaces or is absorbed into the plant. Thus, it is the difference between the precipitation actually occurring over an area and that which reaches the ground. Horton [1919] presented the first comprehensive discussion of the interception process and summarized data collected by himself as well as data published by others. He observed that interception loss was the sum of (1) the stored on the plant surfaces at the end of a storm (and subsequently returned to the atmosphere by evaporation) and (2) the evaporation from wet plant surfaces during a storm.
