InChina, the most serious desertification occurs in agro-pastoral transition zone. Considering the consistencyof socio-economic factors, Ejin Holo county in Inner Mongolia was selected out to analyze the desertificationcauses in this paper. Results showed that erratically climatic factors provided fragile background and drivingforces for desertification processes, and sand-covered surface and its underlying materials and specificgeomorphologic features have a great contribution to desertification processes as well. Socio-economicdevelopment, especially the traditional land management, the landuse patterns and the increase of livestockand human population were the root causes for desertification occurrence and expansion.展开更多
