森林植被层作为水文环境要素，对降水、蒸散和径流等水文通量在空间上的分布特征有着重要的影响作用。
As an important component in hydrological process, forest vegetation influences critically the spatial distribution of hydrological fluxes such as precipitation, evapo-transpiration, and runoff.
降水期间或降水后期地表汞释放通量明显增加。
During or after precipitation event, Hg emission flux increased.
夏季垂直积分的水汽输送通量强辐合区大多位于行星尺度水汽输送大值带中，和降水大值区之间有很好的对应关系。
The strong convergence areas, which are coincide to the big rain belt, mostly lie in the planetary-scale water vapor transport.
