A STUDY ON THE SOIL EROSION PROCESSES IN THE SEMIARID REGION OF INNER MONGOLIA |
| |
| Abstract: | Located in the northwestern edge of China's monsoon climate region, Thestudy area covers more than 500,000Km~2 of the middle of Inner Mongolia,where the water and heat situation is extreamly unstabale. Based on the conventionalfield investigation and analysis, the paper deals with the two-phase processes ofwater and wind erosion and their influences on the semiarid environment, withthe aid of MSS fake-color images (1970s) and the RBV images (1980s) of thetypical study area--Zhunge'er Banner of Inner Mongolia. The paper includes: A. Present situation of soil erosion and its harmfulness in this area. B. The two-phase erosion processes of water and wind and its characteristics, C. Strategic measures suggested to be taken in the prevention of soil erosion. |
