This project (2016YFC0500300), financed by special Central finance, aims to meet the major need, including natural forest protection and green economic transformation, of the northeast forest. To achieve this goal, the project initiates technical development and integration on the crucial bottlenecks, in order to establish a monitoring platform for forest ecosystem and biological resources. In addition, it is essential to break the key technology of natural forest protection, including biological resources amount control, keystone species protection as well as community orientation classification, related to natural forest protection. Based on variety innovation, in situ ecological cultivation, together with the technic development of high value-added products, a whole comprehensive industry chain with a complete criterion will be established, which, as a result, strongly supports the effective protection and the sustainable development in northeastern forest areas. This project is expected to establish a perfect technology ecological system with ecological products fully transformed to industrial products, as more than 29 industrial chains and criterions connected to natural forest protection and bio-resource utilization will be built. Besides, the achievements also contain at least 15 new species, 16 bio-products and 25 invention patents. The ecological system mentioned above will be operated as three large-scale demonstration bases combined with surrounding ecological fragile areas in Yichun forest and Mudanjiang forest area of Longjiang forest industry and Changbai Mountain forest area of the Jilin forest industry. As a consequence, the total area of the project demonstration area will reach more than 100000 hm², and non-forest economy in these areas will increase by 50% with per capita income increasing by an average of 1.5 times.
