| Outline of Final Research Achievements |
Using long-term observational data collected from Lake Shinji from 1993 to 2018, this study analyzed how climate change affects the dissolved oxygen levels (DO) at the lake's bottom. The phenomenon of DO depletion during the summer was found to be largely influenced by fluctuations in water temperature and salinity. Water temperature was strongly linked to local air temperature, while salinity depended heavily on river inflow. These factors were thoroughly examined using a random forest model to understand their interactions.

| Academic Significance and Societal Importance of the Research Achievements |
この研究により、気候変動が宍道湖の水質、特に湖底のDOに与える影響を科学的に解明し、持続可能な水域管理と生態系保護のための重要なデータを提供した。地域の気候変動適応策の策定に貢献することが期待される。また、気候変動による水温と塩分の変動を詳細に追跡することで、将来の環境変化に対応する具体的な対策を提案する基礎を築いた。これは地域コミュニティや政策立案者にとって貴重な情報源となり、広範な社会的影響を持つことが確認された。
