摘要: Detecting near-surface soil freeze-thaw cycles in high-altitude cold regions is important for understanding the Earth's surface system, but such studies are rare. In this study we detected the spatial-temporal variations in near-surface soil freeze-thaw cycles in the source region of the Yellow River during the period 2002-2011 based on data from the Advanced Microwave Scanning Radiometer for the Earth Observing System
