Change Research and Cause Analysis of Inland Lakes in Tibet Based on MODIS Image
Abstract:According to the 2002-2009 MODIS satellite remote sensing data and 2000-2009 meteorological data such as temperature,surface temperature,precipitation,relative humidity,the article concludes that the lake area change is significant in Tibet.The area of Selincuo lake,Dangreyongcuo lake,Zharinanmucuo lake present enlarging trend,respectively 241.97 km2,12.8 km2,11.69 km2 in 8 years;The area of Namucuo lake and Yangzhuoyongcuo lake present reducing trend significantly,respectively 52.17 km2,96.61 km2.The rising of temperature and surface temperature caused snow ice melting and permafrost shallow,which are the root causes of lake area larger.While precipitation reduced is the root cause of lake area reduced.In addition,several typical Tibetan inland lakes are little change in ice-formation time.
