国内外冰川变化对水资源影响研究进展

冰川是重要的淡水资源,其变化不仅对高山及周边地区水资源有重要影响,而且还是影响海平面上升的重要因素,从而成为人们关注的焦点。论文总结了国内外相关研究进展,讨论了研究中存在的主要问题,认为国内的研究范围与深入程度与国外相比仍存在很大差距,突出表现在冰川融化对水资源影响的作用过程与机理研究很少,预测模型在种类、概念框架及技术手段等方面发展滞后。未来西部冰川水资源变化的社会经济与环境影响是西部大开发必须考虑的内容,因此急需加强相关监测与研究。

Progress in the Research on the Impact of Glacial Change on Water Resources

Glacier is an important kind of fresh water resources. The glacier change not only affects obviously water resources in and around mountain area, but also contributes greatly to sea level rise. Thus, it becomes the focus of attention. Reviewing international and domestic studies, this article puts forward that there is still a big gap between native research and foreign ones in scope and depth. Especially, there are few studies on the process and mechanism of melt-water production and forecast models are lagging behind in types, conceptual framework and technical means. The impact of west glacier water resources change on socioeconomy and ecological environment must be taken into consideration in the process of Western Development, and it is urgent to strengthen related monitoring and researches.
