Research Abstract

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.
