Abstract:: Study on the precipitation distribution laws of 3 forests of the mixed forest of Larix and Betula, the mixed forest of Populus and Betula, the mixed forest of Pinus and Mongolicain in North Mountain of Hebei Province. The results indicated that: during the period of observation, along with the increase of rainfall, the throughfall, stemflow and crown interception increase, but the crown interception rate decreases; throughfall of 3 forest stands were 115.31 mm, 115.08 mm, 125.94 mm, accounting for 68.94%, 68.81%, 75.31% of total rainfall; stemflows of 3 forest stand were 4.35 mm, 5.90 mm, 6.24 mm, accounting for 2.56%, 3.47%, 3.67% of total rainfall. The relationships among throughfall, stemflow, crown interception and total rainfall could be described significantly by a linear function. This article refers to interception conception model directly, which can effectively predict the interception capability of the forest ecosystem in North Mountain of Hebei Province.
