东北次生林生态系统保护与恢复技术探讨

Discussion on the protection and restoration technology of secondary forest ecosystems in Northeast China

东北森林在国家生态文明建设、生态环境保护、社会经济发展等方面发挥着重要的作用。本文在分析东北林区森林资源现状的基础上,指出东北次生林生态系统目前存在的问题,指明东北次生林生态系统的发展方向;结合未来三十年全国森林经营规划与国家天然林保护工程等,提出东北次生林生态系统保护、恢复与利用技术及对策,探讨了"后天保时代"(天然林保护工程结束以后)的次生林经营与保护,为东北林区的可持续发展指明了方向。

As an important ecological barrier,forests in Northeast China play critical roles in national ecological civilization construction,environmental protection,and socioeconomic development.Based on the analysis of current situation of forest resources in Northeast China,the current problems and the development direction of the secondary forest ecosystems were proposed.Furthermore,according to the National Forest Management Plan for the coming thirty years and National Natural Forest Protection Project（NNFPP）,the technology and measures of protection,restoration and utilization for the secondary forest ecosystems were put forward,and the management and protection of secondary forest ecosystems during the period of ＂post-NNFPP ＂were also explored.All of these would be conducive to sustainable development of forests in Northeast China.
