| Research Abstract |
We aimed to evaluate the climate change impacts on the vegetation dynamics in alpine ecosystem and to clarify the changing mechanisms. Expansion of dwarf bamboo and drought stress caused the rapid decrease in species diversity and declining alpine vegetation. We developed new methods to quantify the vegetation changes using air-photographs and to evaluate the changes in soil moisture conditions using remote sensing data. Furthermore, we developed theoretical model to predict a drastic vegetation change caused by climate change.
