| 摘 要： | 通过对柞桦林与其采伐迹地小区径流对比试验表明:柞桦林采伐后,林冠层截留功能丧失,灌草层、枯枝落叶层截留有所增大,地表径流系数增大73.3%,说明采伐对林地的产流有一定的影响;观测结果表明,柞桦林比采伐迹地产生的地表径流、壤中流少;在降水量少于50mm的情况下,柞桦林地一般不出现壤中流。

| Abstract: | Through experiment of ratio of runoff plots of oak and birch forest with deforested land,result shows that: after cutting of oak and birch forest,interception function of the forest canopy lost;interception of shrub & grass layer and litter layer somewhat increased;surface runoff coefficient increase by 73.3%;it illustrates that cutting have certain effect on runoff of forest land;observations indicate that surface runoff,subsurface flow formed by oak and birch forest are less than that by deforested land;interflow generally do not appear in oak and birch forest in the case of the precipitation of less than 50 mm. |
