Impact of regions, vegetation types and density on soil erosion in Beijing mountain forest, China
Regions, vegetation types and density are expected to affect runoff and soil erosion processes in mountain forest. Models are typically applied to estimate these impacts. Data used were collected from 23 sampling plots (standard thectare units) in the Nature Reserves and State/National Forest in Beijings mountainous area. Multilevel regression model was used in developing these models. The multilevel modeling technique is perfectly suited for this study because of the hierarchical structure in data and in the various indicators of ecosystem structure and function. The results suggest that different regions, vegetation types and density have certain and different degrees of effects on soil erosion of forest land. The resulting models can be directly used to support best forestry management practices and to provide guidance in monitoring system design for properly recording ecosystem structural and functional changes in response to anthropogenic and natural perturbations.
