On 8-9 December 2017, the annual meeting to sum-up the 6th sub project: Optimization and Regulations of Regional Structure of Balance between Lumber Production and Ecological Functions was held in IAE. The sub-Project was co-undertaken by IAE, Institute of Forest Ecology and Environmental Protection, Chinese Academy of Forestry Sciences, Shanghai Jiaotong University and Beijing Normal University. Peer experts Prof ZHU Jiaojun, FANG Yunting, the sub-project leader Prof YAN Qiaoling and major members of the sub-project, totally about 20 persons were presented.

Prof YAN Qiaoling reviewed the basic background of the sub project, detailed the work advancement in the one and a half year, implementation of the assessment indexes and plan for the next step. The leaders of the 7 task group reported their work development and plan for next step. The peer specialists had a discussion on the reports and agreed that the task and goal of the sub-project was well accomplished and also gave constructive suggestions for the coming work. The specialists hoped that the work focused on the key tree species and produce achievement as soon as possible, better accomplished the assessment indexes and task, to be ready for the middle-period assessment in 2018.

The sub-project was the continuation and deepening of 973 project Structure, Functions and Regulations of China’s Major Forest Plantation Ecosystems. It took larch, Chinese Pine, Masson pine and Chinese fir plantations as research object, systematically assess the current situation of lumber production and water conservation and Carbon sequestration, quantify the trade-off/synergic relationships between lumber production and ecological functions, establish the forest regeneration ways, put forwardstrategies in ecological functions promotion and optimization and regulation of regional landscape so as to provide scientific bases for the sustainable development of China’s forest plantations.
