Outline of Research at the Start

寒冷乾燥地の放牧地生態系における温暖化影響の解明を目指し、モンゴル草原をモデル地域とした研究を展開する。特に、早春期の温暖化影響に焦点を当て、草原の様々な生態系機能や生態系サービス(植物成長や草原の種多様性、生態系の窒素・炭素循環、植物の飼料価値や家畜生産)に対する影響を包括的に解明する。野外温暖化操作実験、室内環境操作実験、長期観測データの統計解析といった異なる研究手法を組み合わせることで、生態系の変化を異なる空間的・時間的スケールで重層的に解析する。本研究を通して、温暖化応答のプロセスの理解から生態系の将来予測まで、モンゴル寒冷乾燥草原における温暖化影響の総合的理解を目指す。

Outline of Final Research Achievements

To elucidate the effects of global warming on rangeland ecosystems in cold and arid regions, we conducted research at various temporal and spatial scales targeting the Mongolian steppe. Comprehensive analysis of all results obtained from field surveys, field experiments, and analysis of long-term monitoring data in Mongolia suggests that global warming is likely to reduce grassland production in the Mongolian steppe through soil drying, and in conjunction with a decline in the nutritional value of forage species, this is expected to have adverse effects on livestock production. Grassland recovery through grazing exclusion is expected to be reduced quantitively by climate change though unaffected in terms of quality. These climate change impacts are likely to vary by region and be influenced by changes in precipitation.

Academic Significance and Societal Importance of the Research Achievements

本研究で明らかになったモンゴル草原の温暖化応答には、様々なスケールで学術的・社会的な意義が認められる。ローカルには、モンゴル草原における牧畜生産の変化予測に寄与するという社会的な意義があり、モンゴル草原の植物量が砂嵐や黄砂の発生と関係していることから、風下の東アジア地域の環境予測に関わる知見を提示したという学術的な意義もある。さらにグローバルに見ると、地球の主要な炭素シンクの1つである草原生態系の温暖化応答を解明し、地球の炭素循環の将来予測に寄与するという学術的な意義が挙げられる。
