Broad-leaved Korean pine forest; global change; biodiversity; forest productivity; forest succession
The temperate forest ecosystem in China is an important part of the ecological barrier in Northeast China. It not only breeds abundant biodiversity, but also is an important timber resource cultivation base and an important support for China to cope with climate change. Due to unreasonable over-harvesting and utilization, the structure and function of temperate mixed forests have been seriously affected, which has significantly affected the regional ecological security. The Research Station of Changbai Mountain Forest Ecosystem, Chinese Academy of Sciences (Changbai Mountain Station), takes revealing the structure, function, and evolution process of the original broad-leaved Korean pine forest in temperate zone of China as the core, carries out long-term monitoring and experimental research, finds that the old forest still has the ability of sustainable carbon sink, and reveals the number of vegetation, the number of big trees, the water conductivity and anti-embolism ability of trees have important effects on forest productivity. It is clarified that the increase of CO 2 concentration and N addition can increase the carbon sink and carbon sequestration ability of ecosystem through control experiments. The role of mast seeding mechanism and scale in forest community construction is discovered, it revealed that the environment filtration, diffusional limitation, and random dilution are the main mechanisms for the formation and maintenance of biodiversity in broad-leaved Korean pine forests, and the relationships between abovegroundunderground and biodiversity-productivity in the process of forest community succession are explored. The research results provide theoretical support for revealing carbon sinks of forest ecosystems and their formation and maintenance mechanisms, promoting the restoration of structures and functions of disturbed temperate forest ecosystems, and building regional ecological security. At the same time, Changbai Mountain Station has cooperated with domestic and foreign scientific research institutes, colleges and universities, developed and demonstrated the decision support system of forest ecosystem management in cooperation with the local forestry bureaus. Changbai Mountain Station has become an important research base of Forest Ecosystem Science in temperate zone of China, and also a scientific research supported platform of integrated forestry industry, education, and research, as well as cradle and incubator of ecology and forestry talent in China.
