| 摘 要： | 1999和2003年在念青唐古拉山冰川考察期间,采用GPS对拉弄冰川末端位置进行了测量,并将将测量结果与1970年航摄冰川末端位置进行对比分析.结果表明:1970-1999年拉弄冰川末端退缩了285m,平均年退缩量9.8m;1999-2003年拉弄冰川退缩13m,平均年退缩量3.25m.由于冰川对气候的响应有一定滞后性,近年来气候持续变暖将使拉弄冰川继续保持退缩状态.

| Abstract: | During the Sino-American Glacier Expedition to Nyainqêntanglha Range in 1999 and 2003, the Lanong Glacier was investigated and its terminus location was measured by means of GPS technique. Compared with the map that was aerial photographed in 1970s, it is found that the glacier has retreated 285 m from 1970 to 1999, and 13 m from 1999 to 2003, equivalent to a retreat speed of 9.8 m·a-1and 3.25 m·a-1respectively. These suggest that climate there has mainly been in warming since the 20 century. Because the response of glaciers to climate change has a retardation, the Lanong Glacier retreat will continue in the future due to climate still being warming in recent years. |
