Abstract: The vegetation restoration in the wind disaster area in Changbai Mountains Nature Reverse plays an important role in the stable development of forest ecosystem and the protection of biodiversity, which has been an important research issue in the Reverse. Based on the field investigation on the current status of vegetation restoration in the wind disaster area, this paper quantified the stability of forest ecosystem by a spatially explicit way, and evaluated the effects of different restoration measures on the vegetation restoration in short and long term by using forest landscape model. The results showed that reforestation could efficiently improve vegetation restoration, especially in long term. Therefore, to control the unstable factors in ecosystem and reduce the spread ability of unstable factors could make the unstable and sub-unstable ecosystems convert to stable ecosystem. For these purposes, it would be needed to reforest with a supplement of natural restoration and to create good conditions for the development of a plant community to a complete ecosystem with local species composition to realize the local  natural vegetation cover as the ultimate goal.
