摘　　要：通过观测我国东北东部天然次生林对降水的分配效应,结果表明:降雨量在1.69~24.36 mm时,森林各水文分配效应总体表现为穿透雨量>地表径流量>树干茎流量>林冠截留量。随降雨量和降雨强度的增加,穿透雨量、地表径流量和树干茎流量随之增大。当降雨量较小(1.69~4.91 mm)时,穿透雨量、地表径流量和树干茎流量随降雨量的增加呈低速增加趋势;当降雨量较大(4.91~24.36 mm)时,其增加速度随降雨量的增加而加快。The distribution effect of natural secondary forest on precipitation in the eastern part of Northeast China was observed.The hydrological distribution effect of the forest was generally showed that through fall>surface flow>stem flow>canopy interception with the rainfall in the range of 1.69-24.36 mm.The through fall,surface flow and stem flow increased with the increase of rainfall and rainfall intensity.With the rainfall in the range of 1.69-4.91 mm,they increased at the low speed with the increase of rainfall.With the rainfall in the range of 4.91-24.36 mm,the increase accelerated with the increase of rainfall.
