Influences of climate change on area variation of Qinghai Lake on Qinghai-Tibetan Plateau since 1980s

Abstract Qinghai-Tibetan Plateau is the most sensitive region to global warming on Earth. Qinghai Lake, the largest lake on the plateau, has experienced evident area variation during the past several decades. To quantify the area changes of Qinghai Lake, a satellite-based survey based on Landsat ima...
