Today, many environmental problems are taken up frequently in news media. People's attention is focused about a scenario of a change of the near future which occurred within 50-100 years. In our study, vegetation responses for the earth environmental change for not only a short-time scale dynamics but also a long-time scale one, which around 1000-10000 yBP. In general, many fluid dynamics variables are mutually affected in the real meteorology system, so large-scale computer resources are required to compute a numerical simulation in sufficient accuracy. In this paper, in order to avoid too much complexity, we discuss a story of natural responses of vegetation that limits in the qualitative discussion range. Results of this study are, (1) geographical feature mainly an adiabatic lapse effect of temperature over the altitude brings influence on extinction of a plant community, (2) there is a time lag between the climate change and vegetation patterns change, so it makes difficult to understand of natural vegetation responses.
