亚洲高山区冰湖水位数据集（2019-2023）

随着亚洲高山区冰川加速消融，冰湖的数量和规模不断扩大。这些冰湖不仅影响冰川动态，还对下游社区及基础设施构成潜在威胁，同时也是重要的水资源储备。然而，当前对这些冰湖水位变化的认识仍十分有限。本研究通过分析2019年至2023年的监测数据发现，冰湖的年际水位变化主要取决于冰川融水补给量与湖泊闭合或开放状态的平衡关系：闭合湖因水分持续积累而扩张，开放湖则通过径流外排维持动态稳定。年内水位波动幅度平均为0.58±0.06米，主要受降水模式和地形坡度调控。对冰湖水位变化规律及其速率的系统揭示，可为冰湖溃决洪水数值模拟提供关键参数，提升溃决灾害评估精度，并为水资源管理策略制定提供科学依据。

With the accelerated ablation of glaciers in the high mountainous regions of Asia, the number and size of glacial lakes have been continuously expanding. These glacial lakes not only affect glacier dynamics, but also pose potential threats to downstream communities and infrastructure, while serving as important water resource reserves. However, current understanding of the water level changes of these glacial lakes remains very limited. This study, by analyzing monitoring data from 2019 to 2023, found that inter-annual water level changes of glacial lakes mainly depend on the balance between glacial meltwater recharge and the closed or open status of the lakes: closed lakes expand due to continuous water accumulation, while open lakes maintain dynamic stability through runoff discharge. The average annual intra-annual water level fluctuation amplitude is 0.58±0.06 meters, which is mainly regulated by precipitation patterns and topographic slope. The systematic revelation of the rules and rates of glacial lake water level changes can provide key parameters for numerical simulation of glacial lake outburst floods (GLOFs), improve the accuracy of outburst disaster assessment, and offer scientific basis for the formulation of water resource management strategies.
