【摘要】After the bursting of Huiten Nor in Hoh Xil Region in September,2011,the topic on whether the water overflowed from the Salt Lake would enter into the Chumaer River and become the northernmost source of the Yangtze River has aroused wide concern from public and academic field.Based on Landsat TM/ETM+/OLI remote sensing images during 2010-2015,SRTM 1 arc-second data,Google Earth elevation data and the observation data from the Wudaoliang meteorological station,the study initially analyzed the variations of the Salt Lake and its overflowing condition and probability.The results showed that the area of the Salt Lake expanded sharply from October 2011 to April 2013,and then it stepped into a stable expansion period.On October 27,2015,the area of the Salt Lake had arrived at 151.38 km2,which was about 3.35 times the area of the lake on March 3,2010.The Salt Lake will overflow when its area reaches the range from 218.90 km2 to 220.63 km2.Due to the differences between SRTM DEM and Google Earth elevation data,the water level of the Salt Lake simulated would be 12 m or 9.6 m higher than the current level when
