GMIE：基于干旱胁迫下灌溉表现及深度学习方法构建的全球最大灌溉范围与中心支轴灌溉系统数据集（2010-2019年）

灌溉作为人类水资源消耗的主要形式，在提升作物产量和缓解干旱影响方面具有关键作用。准确绘制灌溉分布图对水资源高效管理和粮食安全评估至关重要。然而，现有全球灌溉耕地地图分辨率较粗（通常约10公里），且缺乏定期更新。本研究提出一种创新方法，通过干旱胁迫下的灌溉表现作为作物生产力与耗水量的指...

Irrigation, as the primary form of human water resource consumption, plays a critical role in increasing crop yields and mitigating the impacts of drought. Accurately mapping irrigated areas is of paramount importance for efficient water resource management and food security assessment. However, existing global irrigated cropland maps have coarse spatial resolutions (typically around 10 km) and lack regular updates. This study proposes an innovative approach that uses irrigation performance under drought stress as an indicator of crop productivity and water consumption...
