| 摘 要： | 冰川是大自然修筑的"固体水库",在水资源的构成中占有重要地位。新疆地处内陆干旱区,是我国现代冰川面积分布最广的地区之一。冰川和冰川融水为新疆灌溉农业发展提供了可靠的水资源保障。本文根据中国冰川编目及近年来其它冰川研究成果和监测资料,对1960年以来新疆,主要是天山山区的冰川与冰川径流的变化进行了分析。分析表明,受全球气候变暖的影响,上世纪60年代以来至本世纪初,天山冰川的变化整体上以退缩为主,1963-2000年冰川面积平均减少12.5%。但受地理位置和地势条件的影响,不同流域的冰川变化存在着较大的区域性差异。随着冰川的强烈退缩和冰川融水的增加,使得近十余年来新疆天山地区大部分冰川补给河流径流量呈增加的趋势。 |

| Abstract: | Glacier is a kind of "solid reservoir" build by nature,which occupies an important status in the composing of water resources.Xinjiang Uigur Autonomous Region is located in the inland arid region in the northwestern China,in which there are a large number of mountain glaciers.The glaciers and the melting runoff from the glaciers provide an reliable guarantee of water resources for the irrigated farming in the region.The changes of the glaciers and the melting runoff from the glaciers in Xinjian,especially in the Tianshan Mountain since 1960 were analyzed based on Chinese Glacier Catalogue and some others observation data of glaciers.The results showed The changes of the glaciers in Tianshan Mountain presented basically a cancrizans trend because of the impact of global warming since 1960.The glacier areas reduced averagely for 12% during the period from 1963 to 2000.But there were regional differencies due to the impact of geography position and physiognomy conditions of the different valley catchment areas.The runoff in most rivers which are supplied by melting runoff from glacier in the Tianshan Mountain presented an increasing trend along with the increase of melting runoff from glacier resulting by glacier inintense moving back. |
| Keywords: | global warming glacier melting runoff from glacier |
