青藏高原热融湖塘编目数据集

青藏高原是世界上最大的高、低纬度多年冻土带，近几十年来，其多年冻土带迅速退化，其最显著的特征之一就是热融湖塘的形成。这样的湖泊由于能够调节碳循环、水和能量通量而引起了极大的关注。然而，这一地区的热喀斯特湖的分布在很大程度上仍不为人所知，这阻碍了我们对多年冻土的响应及其碳反馈对气候变化...

The Qinghai-Tibet Plateau is the world's largest permafrost zone spanning both high and low latitudes. In recent decades, its permafrost has undergone rapid degradation, and one of its most prominent features is the formation of thermokarst lakes. These lakes have attracted considerable attention as they regulate carbon cycles, water and energy fluxes. However, the distribution of thermokarst lakes in this region remains largely unknown, which hinders our understanding of permafrost responses and their carbon feedbacks to climate change...
