Evaporation From Soil and Thermokarst Lakes Contribute More to Local Precipitation Than Plant Transpiration in Permafrost Regions of the Central Qinghai—Tibet Plateau

Xiaofan Zhu, Shengjie Wang, Tonghua Wu, Jie Chen et autres

Abstract Permafrost degradation on the Qinghai—Tibet Plateau (QTP) directly affects evapotranspiration and moisture recycling processes by changing the underlying land surface conditions. However, the contributions of thermokarst lake evaporation and plant transpiration to local precipitation in permafrost regions of the QTP remain …

Revealing the dual impacts of climate change and grazing on vegetation in Mongolia: Permafrost buffering and the paradox of greening

Yune La, Tonghua Wu, Hasi Bagan, Xiaodong Wu et autres

Mongolia’s ecosystem is highly vulnerable to both climate change and overgrazing, which threaten its ecological stability and livestock husbandry. However, the lack of high-quality data has prevented a thorough investigation into how climate variability and grazing activities jointly affect vegetation growth. Here, …

Evaluation of the Geomorphon Approach for Extracting Troughs in Polygonal Patterned Ground Across Different Permafrost Environments

Amin Wen, Tonghua Wu, Xiaofan Zhu, Jie Chen et autres

As the climate continues to warm, the thawing of ice-rich permafrost leads to changes in the polygonal patterned ground (PPG) landscape, exhibiting an array of spatial heterogeneity in trough patterns, governing permafrost stability and hydrological and ecosystem dynamics. Developing accurate methods for …

Elevation-dependent shift of landslide activity in mountain permafrost regions of the Qilian Mountains

Jie Chen, Jing Zhang, Tonghua Wu, Lin Liu et autres

Increasing landslide activities in cold regions have been attributed to rising temperatures and consequent permafrost degradation. While previous studies have linked permafrost degradation to slope instability, the elevation-dependent effects of this degradation on landslide occurrences in the high-mountain regions of the Qinghai–Tibet …
