Abstract：Based on field investigation and information by GIS and RS, the study attempts to analysie the location and characteristics of the regions near the Capital of China for the prevention of wind erosion. It also studies the causes, distribution and pivotal preventing times of the degraded land. The results show that the major reason for the land degradation is constant aridity such as shortage of rain, excessive use of land, and shortage of protection measures in dry seasons. It is suggested to accept measures suitable to the regions, such as fencing for recovering and rehabilitation and staggered furrows, etc .
