摘　　要：非结构性碳水化合物(NSC)是植物新陈代谢过程中重要的供能物质,NSC库的动态变化不仅反映了植物体内的碳收支状况,还影响着植物的生理代谢活动.为了预测树木甚至整个森林生态系统对未来气候变化的响应和适应能力,本文综述了树木NSC研究的最新进展,重点介绍了NSC库的季节和区域性变化,分析总结了影响树木NSC含量和分配格局变化的主要环境因素.最后还对未来气候变化背景下树木NSC库可能的响应策略和适应状况进行了讨论,展望了未来树木NSC领域的研究方向.Non-structural carbohydrates （NSCs） are an important energy source for the metabolism of plants. The size of the NSC pool is likely to mirror the overall carbon supply status and its dy- namics strongly influences physiological processes in plants. In order to predict the response and adaptation of trees to climate change, this review summarized the current understanding of NSC pool in trees, and mainly focused on its seasonal and spatial variation for analyzing the relationships be- tween environmental factors and NSC allocation. Moreover, the response and adaptation strategies of NSC pool in trees to climate change were also discussed. Finally, some suggestions were proposed for the potential study orientation of NSC pool in trees in future climate conditions.
