中文摘要	在全球气候变化的大背景下,中国西北干旱区气候在过去50 a也发生了相应的变化,对该区域的生态环境已经产生了较大程度的影响。利用西北干旱区128站点19612010年逐日气温降水量资料,结合DEM 数据和GIDS插值分析方法,探讨了西北干旱区气候变化特征及其对生态环境的影响。结果表明:西北干旱区气温普遍升高,但变暖的幅度因季节和地域而存在差异,其中冬季增暖最为明显(0. 506 ℃·10 a~(-1)),夏季增暖缓慢;增温趋势最大区域主要在伊犁河谷、塔城等地区,天山东部和祁连山区变暖趋势也较大,天山中部及沙漠周边地区变暖趋势一般;降水量也呈增加趋势,年和冬季降水增加显著,春季降水有逐步增加的趋势,秋季降水增加则比较缓慢;降水变化趋势山区最大,干旱区东部、沙漠腹地及周边地区有下降趋势;近几十年来西北干旱区气候的暖湿化趋势,导致冰川强烈的消融退缩,对干旱区水资源和生态环境产生重大影响;而沙尘暴频次减小主要与新疆和内蒙古等沙源区向暖湿化发展有关,由暖干化向暖湿化转型对沙尘暴的发生有一定的弱化作用。湖泊水位的升降、面积的变化对气候变化有一定的响应。
英文摘要	Under the background of global warming, the climate in arid areas of Northwest China in the past 50 years has changed correspondingly, giving great impacts on the local ecological environment. Based on the meteorological data of 128 stations from 1961 to 2010, and by using DEM and GIDS interpolation methods, this paper approached the characteristics of climate change in the arid areas of Northwest China and their effects on the local ecological environment. In the study areas, air temperature had a rising trend, but the variation range differed with reason and region. The warming trend was most apparent in winter, but slowed down in summer. Regionally, Ili valley and Tacheng had the greatest warming rate, followed by East Tianshan Mountain area and Qilian Mountains. Precipitation also presented an increasing trend. The annual precipitation and winter precipitation increased significantly, spring precipitation had a gradual increase, whereas autumn precipitation increased slightly. The precipitation varied greatest in mountainous areas, but presented a downward trend in the eastern part of the arid areas, the desert hinterland, and its surrounding areas. The climate warming and wetting trend in the arid areas of Northwest China in the past 50 years led to the glacier melting in summer, giving greater effects on the local water recourses and ecological environment, whereas the decrease of the frequency of sandstorm in the study areas was mainly related to the variations of climate from warmdry to warm-wet in the desert source regions of Xinjiang and Inner Mongolia, which had definite weakening effect on the occurrence of sandstorm. The fluctuations of lake area and its water level were in some extent the responses to the climate change.
