Study On Potential Ravine And Soil Erosion In Maor Mountain Area

The full research of soil erosion in Maor mountain area mainly includes potential ravine and potential soil erosion. Under the background of digital DEM of maor mountain area, and through the program of Avenue in Arcview, the result of potential ravine highly inosculates with the real ravine. With the comparison of potential ravine and real ravine, it can reflect the developing tendency of ravine in this area. Through positioning with GPS and investigation in this area, we can divide the potential ravine of this area into three forms, that is parallel ravine area steep ripe ravine area and evenness swamp area. It can provide scientific reference for forest management and tree planting, and it is a new theory to prevent soil and water loss, and carry through the ravine controlling by people. Based on terrain-. plant, soil and so on, we can analyze the potential danger of soil erosion in this area, and find that plant is the key factor which influence the soil erosion, the more the degree of land using, the more the degree of plant fall to pieces, and the life span of soil will become more and more short. Through the research of soil erosion in this area, we can specify the core area where soil erosion is most dangerous, so we can design the land using effectively. It also can provide a scientific evidence for forest resources management and land using with reason.
