摘　　要：利用新疆102个气象站所监测的气象数据,对区域内1961-2015年的气温和降水的时空演变进行分析。结果表明:平均增温速率为0.3℃/10 a,平均降水增加率为9 mm/10 a;气温变化趋势北疆和东疆增温要比南疆要明显,吐鲁番盆地是增温最剧烈的地区。当前降水处于微弱减小期,天山山区降水明显增多,准格尔盆地和塔里木盆地、吐鲁番盆地降水呈减少趋势。新疆地区降水和气温变化速率在空间存在明显差异,天山和阿尔泰山山区呈暖-湿化趋势,准格尔盆地、塔里木盆地,吐鲁番盆地呈暖-干化趋势。整体上新疆当前处于“暖湿”向“暖干”的转型期,有“暖干”的变化趋势。We analyzed the temporal and spatial evolution of temperature and precipitation in Xinjiang from 1961 to 2015 by using meteorological data from 102 meteorological stations.The results showed that the temperature average warming rate is 0.3℃/10 a.The temperature increase in the northern Xinjiang and eastern Xinjiang is more obvious than that in southern Xinjiang in the trend of temperature change,and the Turpan Basin is the region with the most intense warming.The average precipitation increase rate in Xinjiang is 9 mm/10 a,and there are obvious regional differences in the precipitation on time-space.The current precipitation is in a weak period of decline,and the precipitation in the Tianshan Mountains has increased significantly.However,the precipitation in the Junger Basin,the Tarim Basin and the Turpan Basin has decreased.There are significant spatial differences in precipitation and temperature change rates in Xinjiang.Tianshan and Altai Mountains showed a warm-wet trend,while Junger Basin,Tarim Basin and Turpan basin showed a warm-dry trend.On the whole,Xinjiang is currently in a transition period from“warm and wet”to“warm dry”,and it shows a trend of“warm dry”.
