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.
