中文摘要： 对中国冰川学创立50年以来的成果进行系统总结，并吸取国际冰川学的最新理论，编写了中国第一部冰川学教材- - 《冰川学导论》，并以中国冰川近数十年的变化进行了检验，证明由项目负责人为首的团队研究提出的冰川系统模型能够预测大范围冰川系统变化的趋势。在对整个青藏高原冰川系统结构进行系统分析的基础上，对在升温和降温情景下的冰川变化应用冰川系统模型并作了修正和优化。利用最新遥感资料，结合GIS方法研究羌塘高原和阿尔泰山冰川近数十年的变化表明，前者对气候变化的响应最缓慢，而后者的响应最敏感。对东西天山冰川近期变化对比研究中发现，冰川本身的属性、水交换水平是决定冰川稳定性的重要因素。

英文摘要： On the basis of systematically investigating and summarizing the glacier research achievements both on Chinese glaciology work since founded 50 years ago and among the latest international glaciology documents, the first glaciology textbook of china, the introductory theory of glaciology, was successfully finished. On the basis of the validation of Chinese glacier changes during the recent decades, the research team led by project director confirmed that the model of glacier system could be employed to forecast the variation tendencies of wide range glacier system. On the basis of systematically analyzing of the structure characteristics of the Tibet Plateau glacier system, the model was applied to forecast the glaciers variation tendencies in the future under the climatic scenario of the temperature rising and dropping respectively, after necessarily revision and optimization for the model. Using the latest remote data and combining the method of GIS, the glacier changes on the Changtang Plateau and Altay Mountains were investigated during the past decades. The result indicated that the response of glaciers on the Changtang Plateau to the climate change was relatively slower while the response of glacier on Altay Mountains was relatively more sensitive .Compared with the recent changes of glacier on the eastern and western Tianshan, it was found that the attributes of glacier and the level of water exchange were the key factors to the glacier stability.
