气候变化对山地冰川消融的影响研究
摘 要
随着全球气候变暖的加剧,山地冰川作为地球上重要的淡水储备和气候变化的敏感指示器,正经历着前所未有的消融过程。这一变化不仅威胁着全球水资源的平衡,还深刻影响着山地生态系统的结构和功能。本研究首先分析了全球气温上升、降水模式变化及大气环流变化对山地冰川消融的驱动作用,揭示了气候变化对冰川消融的复杂影响机制。其次,通过对比全球主要山地冰川及中国典型山地冰川的消融空间格局,发现冰川消融存在显著的地理分布与区域差异,且不同海拔高度对冰川消融速率具有重要影响。最后,评估了冰川退缩对水资源供给、生态系统反馈作用及社会经济风险的影响,指出冰川消融将对全球水循环、生态系统平衡及社会经济可持续发展带来严峻挑战。

STUDY ON THE IMPACT OF CLIMATE CHANGE ON MOUNTAIN GLACIER MELTING
ABSTRACT
As global warming intensifies, mountain glaciers, as important freshwater reserves and sensitive indicators of climate change on Earth, are undergoing an unprecedented ablation process. This change not only threatens the balance of global water resources, but also profoundly affects the structure and function of the mountain ecosystem. In this study, we first analyzed the driving effect of global temperature rise, precipitation pattern change and atmospheric circulation change on mountain glacier melting, and revealed the complex influence mechanism of climate change on glacier melting. Secondly, by comparing the ablation spatial pattern of major mountain glaciers in the world and typical mountain glaciers in China, it is found that there are significant geographical distribution and regional differences in glacier ablation, and different altitudes have an important influence on the glacier ablation rate. Finally, the paper evaluates the impact of glacier retreat on water supply, ecosystem feedback and social and economic risks, and points out that glacier retreat will bring severe challenges to the global water cycle, ecosystem balance and sustainable social and economic development.
