中文摘要: 以1976年MSS、1991年TM、2000和2014年ETM +遥感影像资料为信息源,通过RS和GIS技术,提取了念青唐古拉山西段爬努河流域四个时期的冰川信息,并结合周边气象资料进行冰川变化的原因分析。结果表明: 1)1976 - 2014年,研究区冰川面积从621.39km~2减少到481.95km~2,退缩139.44km~2,冰川面积退缩的年平均速率为0.59%·a~(- 1),年平均退缩面积3.67km~2·a~(- 1)。近15a来冰川退缩尤为剧烈,年均退缩速率达到1.03%·a~(- 1)。2)不同时段内冰川退缩速率不同,2000 - 2014年冰川退缩速率整体都大于1991 - 2000和1976 - 1991年,冰川退缩速率呈大-小-大的过程。3)研究区西北坡冰川的面积退缩速率最大,其次是北坡,西南坡最小。4)通过分析冰川变化对气候变化的响应,推断气温上升和降水在波动中变化不大可能是爬努河流域冰川处于退缩状态的主要原因。
英文摘要: Based on the Landsat MSS /TM/ETM + data,we extracted the glacier outlines and analyzed the glacier variations in the Panuhe Basin from 1976 to 2014 by using RS and GIS,combining with the meteorological data near the study area,and the mechanism about glaciers changes were also discussed at the same time. The results showed that:(1)From 1976 to 2014,the whole glacier area in the study district decreased from 621.39km~2 to 481.95 km~2,and the total loss was 139.44 km~2,the annual average retreat area and the annual average rate of retreat were 3.67km~2·a~(- 1) and 0.59%·a~(- 1) respectively. The shrinkage rate of glaciers was accelerated in recent 15 years and the annual average rate of retreat was up to 3.67km~2·a~(- 1).(2)The retreat rate was not the same among different periods,in the overall,the retreat rate of glacier during 2000 - 2014 was much larger than the period 1991 - 2000 and 1976 - 1991,and it showed a " large - small - large" pattern.(3)The glaciers in the northwest experienced the highest retreat rate,followed by the glaciers in the north,while the glaciers in the southwest were the lowest one.(4)Extensive meteorological data on glaciers have shown that the high glaciers shrinkage rate through the years in study area may mainly due to increased air temperature and slight variations on precipitation.
