Abstract:

根据夏季消融期成像的LandsatTM影像和2000-2009年间的MOD10A1数据资料,分析了唐古拉山区冬克玛底冰川反照率的时空变化特征.结果表明受空间尺度效应和现有反演方法的影响,由遥感反演的反照率资料在数值上存在一定的误差,但基本上能够反映冰川反照率的时空变化特征.从空间分布上来看,该冰川反照率随海拔升高呈增大趋势,其中在平衡线附近的变化最为显著;受地形因素的影响,在同一海拔带内部也存在着较大的差异.从年内变化上来看,该冰川反照率日际变化波动较大,且具有明显的季节变化特征.从年际变化上来看,自2000年以来该冰川年均反照率的变化波动较大,总体呈微弱下降的趋势,这主要与年降雪和冰面污化程度有关;不考虑降雪对冰面反照率的影响,2000-2009年间该冰川在消融期的反照率呈逐年减小的趋势,变化速率约为-0.0083·a-1,其原因在于夏季气温的升高和冰面污化程度的加大.
