摘要: 基于世界冰川监测服务处(WGMS)发布的冰川物质平衡数据,对全球40条典型参照冰川物质平衡资料进行分析,结果表明:1984年以来,40条冰川中的36条在观测时段内处于物质平衡为负的状态,冰川普遍退缩,尤其在中纬度比较强烈;全球参照冰川物质平衡的多年平均值为-563 mm,累积物质平衡为-18 590 mm,且2000年之后出现了加速消融的变化趋势;全球参照冰川物质平衡的年代际平均值呈阶梯下降,每10年,物质平衡值下降200 mm左右;由于区域气候变化的差异性以及冰川对气候变化的响应程度不同,冰川物质平衡变化表现出显著的区域特征,物质平衡值由北到南出逐渐增大,空间上呈现出典型的纬度地带性和经度地带性特征;气温是控制冰川物质平衡变化的主要因子,物质平衡过程通常与各地区不同时间尺度的气候波动和变化显著相关。

Abstract: Based on the glacier mass balance data released by the World Glacier Monitoring Service, variation of 40 reference glacier mass balances all over the world were analyzed. It was found that since 1984, 36 of the 40 reference glaciers, have retreated, especially in the middle latitude regions, global glaciers have shown a trend of accelerated ablation after 2000, with a multi-year average of mass balance of -563 mm and a cumulative mass balance of -18 590 mm. The decadal mean mass balance of global reference glaciers have been descending step by step, and the mass balance declining by about 200 mm every ten years, especially from 1990 to 2010. Due to the different regional climate change and the different response of glaciers to climate, the glacier mass balance has shown significant regional characteristics and the mass balance has gradually increased from north to south, showing typical latitude and longitude features. Temperature is the main factor controlling the glacier mass balance change, the variation process of mass balance has been usually associated with climate fluctuation in each regions.

Key words: glacier, mass balance, cumulative mass balance, temporal and spatial variation, control mechanism
