Abstract:: Forestry plays an important role in the atmosphere rainfall redistribution. Throughfall, stemflow and canopy interception of a natural forest stand of Pinus tabulaeformis in Mulan in Hebei Province of China were observed in 2010. The characteristic of rainfall redistribution of Pinus tabulaeformi in the mountainous was analyzed. The results showed that the rainfall, canopy interception and stem flow accounted for 69.07%,29.79%, 3.10% of total rainfall, respectively. Throughfall, stemflow had significant relationship with total rainfall(R²=0.986, R²=0.893). Relation between canopy interception and rainfall could be described by a power function (R²=0.765); according to the regression equation, when the rainfall outside the forest was greater than 0.264 mm, the penetration of rainfall could occur, when rainfall outside the forest was greater than 4.89 mm, the runoff of trunk could occur; canopy in the process of redistribution rainfall played a major role in spatio-temperal redistribution.
