An atmosphere-vegetation interaction model has been developed and improved to elucidate annual variability in energy and carbon exchanges and forest dynamics in sub-boreal forest ecosystems. In several papers of mine, I have shown that the simulation model was found useful to present simultaneous simulations of forest dynamics, surface energy, and carbon exchanges of the forests. In addition, the simulation evaluated the effect of typhoon on annual variability in net ecosystem exchanges in the forests in terms of ecophysiological point of view. From my researches, hence, I have indicated the simulation could be an available tool to assess the functional and structural effects of plants on energy and carbon exchanges with stand development under dynamically changing climate in the near future.

建立并改进了大气-植被相互作用模型，以阐明亚北方森林生态系统能量、碳交换和森林动态的年变化。在我的几篇论文中，我已经证明了模拟模型对于同时模拟森林动态、表面能和森林碳交换是有用的。此外，模拟还从生态生理学角度评价了台风对森林生态系统净交换年变率的影响。因此，从我的研究中，我已经指出，在不久的将来，在动态变化的气候条件下，模拟可以作为一种有效的工具来评估植物在林分发展中对能量和碳交换的功能和结构影响。
