Abstract: The region at the juncture of Shanxi, Shaanxi and Inner Mongolia is one of the most serious regions of ecological imbalance in China. A series of ecological issues in the region, such as vegetation degeneration, soil erosion, soil desertification, and so on, not only threatened local people's livelihood and development, but also affected the environmental quality and economical development of eastern China. Therefore, it is of significance to study the theory and technology of ecological restoration in the region. This paper analyzed the historical and current status of theoretical research and practical application of ecological restoration in the region, and put forward some suggestions on strengthening the researches of the mechanisms of vegetation degeneration, the determination of target communities for vegetation restoration, and the ways of carrying out ecological restoration on big scale area, which would benefit the development of ecological restoration in the region.
