我国石灰岩地区森林培育技术研究进展

石灰岩广泛分布于我国，其特殊的生态特征，促进了石灰岩地区植物区系朝着特有化发展。在总结我国石灰岩地区造林立地分类、适生树种、植苗造林技术和区域营造林综合开发方面研究成果的基础上，提出当前及今后一定时期，应着重加强石灰岩地区先锋造林树种的品种选育、工程造林技术最优化和标准化、区域综合开发营造林模式研究，为加快推进石灰岩地区森林植被恢复进程提供更加有效的技术支撑。

Research progress of silviculture in limestone areas of China

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.
