| 英文摘要 | Changes in Arctic lake extent are critical indicators of regional water balance and permafrost stability. While previous studies have documented widespread lake shrinkage or disappearance under warming and permafrost thaw, it remains unclear whether lake geometric features-such as shoreline length, area, shape complexity, and depth-modulate the lake response to these drivers. This study examined lake area dynamics for more than 4000 lakes across the Yukon and Mackenzie basins using Landsat-derived annual lake area products from 2000 to 2020. We employed boosted regression trees to quantify the contributions of climate change and permafrost thaw to the observed trends and to evaluate the regulatory effect of lake geometric features. Our results revealed that while some lakes expanded, the average trend for individual lakes was characterized by reductions, with the mean rates of-0.20 ha/yr and-0.14 ha/yr in the Mackenzie and Yukon basins, respectively. The shrinkage of lake area mainly driven by climate change and permafrost thaw was regulated by the geometric features of lakes, with lakes having longer shorelines or larger areas demonstrating more pronounced responses to permafrost thaw. These findings emphasize the regulatory effect of lake geometric features on the response of lake area changes to climate change and permafrost thaw, indicating the need to consider lake geometric features when predicting lake evolution in the context of Arctic permafrost thaw. |
