摘要
贡嘎山是我国典型海洋型现代冰川发育中心之一,冰川动态与环境演替关系密切。20世纪80年代初的系统科考,将其东坡海螺沟冰川定位为我国典型海洋型冰川并开展了连续监测,之后逐步建立与完善的野外台站为冰川研究及其相关的环境与生态系统定位监测提供了重要基础平台。本文主要围绕冰冻圈地理学领域,对贡嘎山地区典型海洋型冰川的科考、定位监测及相关研究进行了回顾,并结合近年来国内外冰川学领域的发展趋势,探讨与展望未来在该地区亟需关注的与冰川学科相关的科学问题。
Most glaciers in Mt.Gongga,east edge of Tibet Plateau,physically belong to the type of monsoonal temperate,generally with low altitude of ablation area and highly interacted with environments in their proglacial zones.Due to the strong influence of maritime climate and monsoon,temperate glaciers in Mt.Gongga are characterized by high level of mass balance,low altitude of terminals,strong surface ablation and fast ice flow speed.This has not only impacted the hydrological processes and variation of glacial runoff,but also has driven remarkable dynamics of mountain surface processes and preglacial ecological environment.During the comprehensive scientific expedition to Qinghai-Xizang Plateau in Hengduan Mountains in 1980 s and the Sino-USSR joint glaciological expedition to Mt.Gongga in 1990 s,repeat glacial investigations or short-term observations have carried out on several larger glaciers in Mt.Gongga,with main information of modern temperate glaciers and quaternary glaciations were detailed investigated by field expeditions.With the foundation of Gongga Alpine Ecosystem Observation and Research Station since 1988,detailed monitoring of typical monsoonal temperate glaciers were carried out by the station.This paper gave a review of the monitoring and research progress of monsoonal temperate glaciers in Mt.Gongga.Several research areas,including glaciology,ecology,catastrophology and other environmental sciences that related to the changing glaciers,are introduced and prospected.
