| Outline of Final Research Achievements |
In this study, we developed an ecosystem model that simulates long-term dynamics at centennial to millennial temporal scales. The model was used to evaluate the impacts of land-use change and climate variation on ecosystem structure and functions. Using data on past cropland distribution and climate conditions, we conducted a series of simulations focusing on the changes in productivity and carbon stock. The simulated ecosystem dynamics during the past periods are implicative, allowing us to discuss future change in ecosystems and its impacts on human society.
