中国冰川运动速度研究进展

Progress of the Research on Glacier Velocities in China

我国开展冰川运动速度研究已有50a的历程,依国内现有的山谷冰川运动速度资料为基础,分析研究了中国冰川运动速度的研究现状与取得的主要成果,总结了冰川运动监测的技术方法.结果表明:各大山系的冰川运动速度都在逐渐减小,但减小幅度不同,这与冰川的规模相关.监测方法上以实地测量为主也不断发展新的空间监测方法.未来应该加强冰川运动的机理研究,多种观测方法综合应用于冰川运动监测,保证资料的连续性与完整性.

Glacier velocities have been researched for nearly 50 years in China.But there is no scientific summarization about glacier velocities.In this paper,the current study status,research achievements,and surveying technology about glacier velocities are summed up.In general,China＇s valley glacier velocities are decreasing,with a local difference,which is related to the difference in glacier size.Land-based survey is the basic monitoring method,and advanced aerial methods are adopted by degrees.It is necessary to strengthen ice movement mechanism study,to use ground and aerial observation methods synthetically to monitor glacier movement,and to ensure the continuity and integrality of the surveyed data.
