Abstract Limestone is widely distributed in China.The typical ecological characteristics,such as shallow soil body,serious water infiltration,poor water retention and rich in calcium,promote the flora of endemism developed in limestone area.In this paper the research results on artificial restoration of forest vegetation in limestone area are reviewed,including regional distribution of limestone area,site classification,proper forest plant species,silviculture technology and integrate technology of afforestation.At present and in the future,we should strengthen the study of pioneer plants breeding,optimization and standardization of engineering afforestation technology,regional integrate afforestation pattern in limestone zone,to provide more effective technical support for the advance of the restoration forest vegetation process in limestone area.
