摘要
利用吐鲁番盆地近53a的气温、降水量、日照时数资料对气候变化特征进行分析,并与20世纪80年代以来东疆地区部分县市的气候变化数据进行比较分析,结果如下;吐鲁番盆地近53a来气温和日照时数波动中上升趋势,降水量稍微降低,但是20世纪80年代以来降水量表示增加的趋势,即气候原来的干燥暖化状况改变为湿润暖化趋势。东疆地区比较分析显示,20世纪80年代以来吐鲁番市、哈密市、托克孙县的气候暖湿润趋势,鄯善县却干燥暖方向发展的趋势。该区气候变化由二氧化碳的增加,人类活动的影响,漂土日数的增加有密切相关。
Based on the air temperature,precipitation,sunshine duration data of Turpan Basin nearly 53 years,the characteristics of climate change were analyzed,and the climate change data of east Xinjiang region since 1980s were also comparatively analyzed. The results are as follows,the temperature and sunshine hours of Turpan basin in recent 53 years had the upward trend in the fluctuations,the precipitation slightly lowered,but it had the increasing trend since 1980s,which was said that the climate had changed from dry warming conditions to wet warming. Comparative analysis of east Xinjiang region showed that since 1980s,Turpan,Hami City,Tok Sun County had the warm and humid climate change trend,Shanshan County had the dry and warm change trend. The climate changes of the area are closely related to the increase of carbon dioxide,the impact of human activities,the increase of drift soil days.
