Outline of Final Research Achievements

To propose how to recover already degraded alpine vegetation through the regime shift under climate change especially global warming, we have performed model analyzing based on the state structure quantitative analysis in terms of several dimensionless parameters, referring to field measurement data and recovery experiment data in our research field. It has been found that the plausible values of the parameters in our model can explain the degraded alpine vegetation in our field as a regime shift, and the initial soil water content increased by cutting dwarf bamboo on the ground can recover the favorable stable state structure, and as a result our degraded alpine vegetation can be recovered within a reasonable value of dimensionless parameters in our model.

Academic Significance and Societal Importance of the Research Achievements

数理モデルの中の定量的解析は、同じ量の比の形で無次元化したパラメータを使って行ない、空間スケールに依存しない条件で遂行するという方法論を確立できたことで、大雪山という具体的な場所に限られない、気候変動による高山植生遷移の一般的な解析手段として学術的意義をもつと考えられる。また「ササの刈取り」という方法論の具体的な条件設定(刈取り期間、間隔等)を変えたときの成果を、フィールドの測定データ(土壌水分量の時系列データ等)から推し量るための定量的なシミュレーションの方法を確立し、高山植生が安定的に回復するまでに必要なササ刈取りの継続年数を推定する方法論を見出すことが出来たことの社会的意義は大きい。
