摘  要:
以Landsat影像为依据,通过遥感图像计算机辅助分类和目视解译等方法提取了贡嘎山区1974年、1990年、2000年、2010年冰川边界,并分析贡嘎山区近40a来的冰川变化。结果表明:1974—2010年贡嘎山区冰川面积减小了30.20km2,占1974年冰川面积的11.86%;冰川分布的平均海拔升高了44m。结合气象资料分析认为,升温是研究区近年来冰川加速退缩的主要原因,预计贡嘎山区冰川的退缩速率会进一步加快。

摘  要:
The maritime type glaciers in Gongga Mountain are very sensitive to climate change.Landsat TM,MSS and ETM+ data were used to extract the glacier outlines in 1974,1990,2000,and 2010.And it was concluded that the glacial area decreased 30.20km2(11.86%)and the glacial altitude increased 44min the mountain from 1974to 2010.The main reason for glacial retreat was temperature rise.It is estimated that the glacier retreat rate will accelerate.
