Abstract:

利用1980—2009年气象台站的观测数据、北半球NOAA周积雪产品和2001—2010年500m分辨率的EOS/MODIS积雪产品等多源资料,从不同角度对近30a来西藏区域积雪变化趋势进行了分析.结果表明不同资料分析均显示,近30a来西藏地区积雪不断减少,尤其以近些年较为明显.近30a积雪日数、最大积雪深度总体上呈现下降趋势,尤其是进入21世纪以来,下降趋势非常明显.从秋冬春季节的积雪变化趋势来看,冬、春两季的积雪在减少,而秋季在增多,这些变化趋势都与各季节的气温和降水密切相关.NOAA资料显示,近30a来西藏地区的积雪覆盖面积正在逐步减少;季节变化略有不同,春、秋两季略呈上升趋势,冬、夏两季在减少,且夏季减少趋势较明显.MODIS资料分析表明,近10a来西藏地区的积雪总体呈下降趋势,尤其是2007年下半年开始下降明显.秋季的积雪在增加,冬、春、夏三季的积雪趋于减少,且春季的下降趋势最明显,其次为冬季,夏季的减少幅度最小.不同海拔的积雪都有减少趋势,最明显的是海拔4000~5000m的积雪,其次是海拔5000~6000m段.按地理区域分析,近10a来西藏东、西、中3个区域的积雪都呈减少趋势,其中西部的下降趋势最明显,其次为中部,东部相对较稳定.
