鉴于温带森林对气候变化的敏感性，结合非结构性碳水化合物（NSC）的储备、分配及动态在指征森林应对气候变化不确定性和影响树种纬度分布限界的热点研究态势，本项目选取我国温带地带性植被（红松针阔混交林）建群种（红松）为研究对象，研究红松物种NSC储量、时间动态、空间格局。采用空间代替时间方法，分析气候变数驱动的红松发育过程NSC储量和器官分配比例变化，从植物碳生理视角阐述气候变化背景下温带地带性植物群落建群种的适应性；采用均匀栅格样地方法，辅以红松纬度限界的加密采样，诠释红松物种的空间分布格局及其气候变数影响趋势，探索树种纬度分布限界的NSC响应机制。为大尺度评估气候变化背景下温带森林碳收支和遥感空地反演参数获取提供支持。

Given the sensitivity of temperate forests to climate change, Integrating of non structural carbohydrate (NSC) reserves, distribution and dynamic is one of the research hotspots in specie distribution and uncertainty in forest response to climate change. Taking the Korean pine, one of the dominant species of the temperate broadleaved Korean pine mixed forest, as the object, This project, by measuring of NSC reserves, spatial distribution and temporal dynamic, aims to study the adaptation of Korean pine to climate change; By uniform grid sampling, supplemented by High density sampling at latitude limit, to study the spatial pattern and the influence of climate change. Eventually, to search the NSC mechanism of the dynamic distribution boundary of the Korean pine. The output will support the evaluation of forest carbon budget of temperate forest and remote sensing inversion at large scale under changing climate.
