摘要:

在全球变暖背景下,亚洲高山区冰川正在加速消融退缩。从冰川的物理变化机制,数值模拟冰川变化的过程,是揭示冰川变化机理的关键,也是研究冰川对气候的响应以及预测冰川变化的重要途径,更是应对冰川变化引发水文、生态、和环境效应的重要前提。作为冰川变化研究的前沿方向和热点领域,数值模拟一直是山地冰川研究的核心任务,近年在对亚洲高山区冰川研究中进展迅速。本文首先简要介绍了对山地冰川进行数值模拟的基本原理和方法,然后简要回顾了近年来亚洲高山区冰川数值模拟的研究现状,最后基于目前的研究与认识,提出我国在冰川数值模拟研究的薄弱环节并进行了展望和设想。本文可为建立、发展冰川数值模型,尤其是亚洲高山区山地冰川数值模拟研究提供基础知识和参考。

Abstract:

Glaciers on the Asia High Mountains are melting and shrinking rapidly in a global warming condition. For a better understanding the glacier variability and its response to climate change, it is imperative to simulate the glacier variability based on the physical mechanism process. As the frontier direction and hot field of glacier change research, numerical simulation has been the core task of alpine glacier studies. In the past decades, much progress in glacier variability has been made by numerical simulations. Here, we briefly introduced the basic principles and methods of numerical simulation on mountain glaciers, and then briefly reviews the research progress of numerical simulation of glaciers in the Asian High Mountains in recent years. Finally, based on the current research and understanding, we put forward a prospect for simulating the glacier variation in future.

Key words: Asia High Mountains, glacier, numerical simulation, mass balance, flow model
