Research Progress of the Complex Response of Vegetation Topographic Evolvement and Soil Erosion in H

Article Summary   by:TsingHua     Original Author: Science Technology and Engineering

The vegetation, which is the essential element in effecting ecological environment quality, is important to the soil erosion and topographic evolvement. Aiming at the problem of recent vegetation of Loess Plateau, The hilly areas of the Loess Plateau as the key study object are takeed.The research method of different spatial features replacing different temporal succession serial analysis is used, investigated the different topographic character, the vegetation type and community character of the abandoned land, and taked the combination of the manual rainfall, observing establishment and the analysis of the observed data out the door, the aerial imagine and the relief map, the combination of the topographic evolvement and soil erosion theory. It also discusses natural vegetation succession, slope donga topographic evolvement and soil erosion, the influence of gully edge topographic erosion evolvement by the slope donga topographic conformation and current character, as long as points out the vegetation succession law, the complex and influencing mechanism of the slope donga topographic evolvement speed and soil erosion. The study fruit of this article is significant to deepen the research of the vegetation construction, topographic growth and soil erosion theory. It also can provide scientific information on exploring vegetation construction in Loess Plateau and soil and water conservation governing and decision-making.
