Withered branches and dead leaves in the forest play an important role in amelioration of soil, interception of rainfall, reduction of splashed erosion of raindrop and control of soil loss.

林地枯落物对改良土壤、截持降雨、减少雨滴溅蚀、防止水土流失等都具有重要作用。

The results showed that the variation of forest soil water was caused mainly by variations of forest soil conditions and uneven interception of rainfall by tree crowns that, varies with seasons.

结果表明，森林土壤水分的变异主要来源于林地土壤条件的变化及树冠对降雨的不均匀截留，且随季节而变化。

The role of interception to rainfall by Canopy of vegetation decreased and weakened splash on soil erosion, and different vegetation restoration displayed differently.

植被冠层对降水的截留作用削弱了雨滴对土壤的溅蚀，不同植被恢复类型的截留作用表现各异。
