区域水分利用效率时空演变特征及干旱影响分析
Spatiotemporal evolution characteristics of regional water use efficiency and analysis of drought impacts
摘要
Abstract
The water use efficiency of watershed ecosystems is a core indicator reflecting the coupling relationship between carbon and water cycles.Exploring its spatiotemporal evolution characteristics and the impact of drought on it is crucial to reduce the impact of drought on watershed ecosystems.Based on a 1 km×1 km grid,the monthly scale water use efficiency was analyzed using MK-Sen trend analysis and Hurst index to reveal the spatiotemporal evolution of water use efficiency in the watershed ecosystem.The impact of drought on water use efficiency in the watershed ecosystem was quantified using drought indicators and loss indicators,aiming to provide a reference for improving the drought resilience of the ecosystem and efficiently regulating regional water resources.关键词
