- 요약Water and carbon are fundamental drivers of terrestrial ecosystem processes. Their coupling through plant stomata has implications at multiple scales, spanning individual plant physiology, ecosystem function, and global carbon cycling. Water-carbon coupling dynamics are shifting under a changing climate and intensifying droughts, with implications for agricultural productivity and climate mitigation goals. Advances in remote sensing and machine learning provide new opportunities to analyze these dynamics and support ecosystem resilience through sustainable management.This dissertation examines water-carbon coupling at multiple scales to better understand trade-offs between water use and carbon assimilation under drought. Combining literature synthesis, field experiments, and remote sensing analyses, the research herein explores how water limitation affects carbon uptake rates in natural, experimental, and agricultural contexts. Results show that water availability plays a critical role in regulating carbon cycling, with groundwater drought and surface water scarcity reducing carbon fixation and sequestration over space and time. Sustainable management practices, such as crop diversification, can benefit ecosystem resilience to drought by improving improving agricultural water-use efficiency in water-limited regions. Together, these findings provide a wholistic exploration of how plants and ecosystems optimize water-carbon coupling under varying conditions and management.By integrating plant, ecosystem, and landscape-scale perspectives, this work advances understanding of water-carbon interactions under a changing climate. The findings contribute to strategies for sustainable resource management and ecosystem resilience in water-limited regions around the world.
