摘要:
流域生态系统水分利用效率是反映碳水循环耦合关系的核心指标,探明其时空演变特征及干旱影响特性,对降低干旱对流域生态系统的影响至关重要。基于1 km×1 km网格的月尺度水分利用效率,利用MK-Sen趋势分析与Hurst指数揭示了流域生态系统水分利用效率的时空演变规律,借助干旱指标和亏损量指标,量化了干旱对流域生态系统水分利用效率的影响,以期为提高生态系统抗旱韧性和高效调控区域水资源提供参考。
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.
