Recent dynamics of alpine lakes on the endorheic Changtang Plateau from multi-mission satellite data

摘要: Abstract Monitoring of the alpine lakes on endorheic Changtang Plateau is vitally important in understanding climate impacts hydrological cycle. Existing studies have revealed an accelerated lake expansion during 2000s compared with prior decades. However, partial hiatus recent Landsat archive affected continuation changes decade. Here we synergistically used imagery from and Huanjing satellites to enable a detailed monitoring area dynamics Plateau. Our results present that continued expand at rapid rate 340.79 km 2  yr −1 (1.06% yr , p  (0.92% (1.47% p = 0.08), respectively, indicating glacier retreat alone may not fully explain expansion. Intra-annual variations selected 24 large fluctuated within 0.22–2.46% (in coefficient variation) for glacier-fed 0.17–2.36% non-glacier-fed lakes. Most these expanded unfrozen period (from May/June October) reached their maximum extents September or October. By spatially associating our variables, observed more related precipitation than temperature, although future efforts are needed comprehensive picture changing mechanisms.
