Key Issues on Cryospheric Changes,Trends and Their Impacts

根据在世界上在中国和 cryospheric 科学的当前的地位分析 cryospheric 研究的重要性，这篇论文在中国处理关键问题和现在的 cryospheric 科学的主要内容。当前处理的关键问题是：我) 响应在水资源评价的气候变化和规模变换的冰河的不同类型的机制；ii ) 在冻结的土壤和植被之间的水和热交换当模特儿；iii ) 在象结合气候一样的 cryosphere 的物理过程的 parameterization 当模特儿。为了获得这些的完整的澄清，给问题调音，下列三个方面的工作应该被加亮，即， cryospheric 过程和回答到气候变化， cryospheric 变化的影响，和改编为 cryospheric 变化的策略。引证 Qin， D. ，和丁·伊， 2010：在 cryospheric 变化，趋势和他们的影响上给问题调音。副词。Clim。变化物件， 1， doi：10.3724/SP .J.1248.2010.00001。

On the basis of analyzing the importance of cryospheric researches in China and current status of cryospheric sciences in the world, this paper addresses key issues and main contents of present cryospheric sciences in China. The key issues currently addressed are： i） mechanisms of different types of glaciers in response to climate change and the scale-conversion in water resources assessments; ii） modeling of water and heat exchanges between frozen soil and vegetation; iii） parameterization of physical processes in cryosphere as well as coupling with climate models. To gain full clarification of these key issues, works of the following three aspects should be highlighted, i.e., cryospheric processes and responses to climate change, influences of cryospheric changes, and adaptation strategies for cryospheric changes.
