In order to explore the process of Larix principis-rupprechtii Mayr forest on rainfall redistribution, throughfall, canopy interception and stem flow were monitored in Larix principis-rupprechtii Mayr forests of the north valley in Mulan-Weichang Forestry Management Bureau. The results showed that: (1) throughfall and interception ratio of rainfall outside of forest volume were larger, the trunk runoff proportion was very little, which was 59.44%, 39.20%, 1.36%, respectively; (2) throughfall and rainfall appeared to be a linear relationship (R2=0.988 6), the canopy interception and rainfall outside the forest also had the obvious power function relationship (R2=0.755 9), trunk diameter flow had remarkable linear relation with the rainfall outside the forest (R2=0.755 9) at the extremely significant level (p < 0.01); (3) according to the equation on the throughfall and the rain outside of forest, when the rainfall was higher than 1.81 mm outside the forest, the throughfall would occur, based on the equation on rainfall outside the forest and tree trunk runoff, the trunk runoff would produce when rain outside the forest was greater than 5.18 mm. Canopy played a very important role in the redistribution of rainfall, the formation of a secondary rain.
