- Title:
- Effect of Forest Cover on Sediment Yield Produced by Erosion in Different Spatial Scales
- Keywords:
- forest cover; sloping land; scales; sediment yield produced by erosion
- 分类号:
- S157
- 摘要:
- 根据1991～2000年的森林水文定位观测成果,主要采用对比试验的方法,对人工径流小区尺度(100m2)和对比自然坡面尺度(0.9hm2)水源林的产流产沙特征进行了深入分析,在此基础上初步分析了水源保护林对侵蚀控制的空间尺度效应。
- Abstract:
- According to the locating observation result of forest hydrologic properties from 1991 to 2000,the characteristics of the runoff and sediment yield of artificial runoff plot scale(100 m2)and natural sloping scale(0.9 hm2)were analyzed deeply by taking the method of contrasting experiment.Based on these,the effect of forest cover of headwater on erosion control was primarily analyzed.
