摘要
利用新疆吐鲁番地区气象代表站点1960~2011年的年平均气温,年最高最低气温,平均气温距平以及年降水量等数据资料,分析近52年以来吐鲁番市的气候变化特征。结果表明：吐鲁番市气候明显变暖,年平均气温升高率0.475℃/10a。其中近10年的年平均气温与20世纪60年代平均气温相比增高了1.75℃。2007年是年平均气温历史最高时期,平均气温为16.3℃。吐鲁番市降水量总体上变化趋势不是很明显,年平均降水量的线性变化倾向率为0.225mm/10a,1986年是降水量最多时期,降水量为86.0mm。该地区气温升高以及降水量降低对人类的工农业生产导致了很大的负面影响。
According to the annual average temperature,annual maximum and minimum temperature,mean temperature and annual precipitation data of 1960 ~ 2011 from the representative meteorological stations in Turpan area,Xinjiang,we analyzed the climate change characteristics in Turpan for the past 52 years. The results show that： the climate in Turpan city was becoming warm,the annual average temperature rising rate was of 0. 475℃ /10 a. The annual mean temperature in the recent 10 years increased by 1. 75℃ compared with that of 1960s. The annual average temperature of 2007 was the highest in historical period; the average temperature was of 16. 3℃.The precipitation change in Turpan city was not obvious; the linear tendency of annual average precipitation rate was 0. 225 mm /10 a. Year of 1986 had the most precipitation of 86. 0mm. The temperature rising and precipitation reducing caused great negative impact on human industrial and agricultural production.
