补充资料：截留
| 截留 interception 植物茎叶枝干拦截降水的现象。降雨时，最先落在植物茎叶上的雨滴几乎全部被茎叶枝干表面截留，聚集起离散的水珠，随后水珠相互连接，形成铺盖在枝叶面上的薄水层 ，水层不断增厚，当水层的重力超过枝叶与水之间的附着力时，一部分水向下跌落或沿枝茎流到地面。此后，枝叶上的水分不断被新落下的雨水所代替，只有留存在枝叶上的那部分水，才成为植物截留。降雨停止后，截留的水分耗于蒸发。植物截留量有两部分，一部分是降水过程中从枝叶面蒸发的水量，另一部分是降雨终止时存留在植物枝叶面上的水量，这部分水量，最后也耗于蒸发。截留量的大小与降水量、降雨强度、降雨历时、风、植物种类和枝叶茂密程度有关。在径流形成中，截留是一种损失，据观测试验资料，茂密的植被一年中截留的水量可达年降水量的25％～30％。它减少达到地面的降水量，即减少地面径流。截留量主要通过在树冠、树干 、树下和林间空地分别设置雨量计，观测对比确定。 |
