中文摘要: 根据塔里木灌区阿拉尔气象站1961年1月~1999年12月的气温及降水资料,分析了塔里木灌区近40年的气候变化,得出近40年来塔里木灌区年降水量呈上升趋势(4.60mm/10年) ,秋季降水量却呈下降趋势(-3.45mm/10年) ;年平均气温呈上升趋势(0.065℃/10年) ,冬季变暖的趋势(0.849℃/10年)远大于夏季变凉的趋势(-0.171℃/10年) ;年极端低温的上升趋势(0.569℃/10年)大于年极端高温的下降趋势(-0.095℃/10年)。可以70年代末为界将近40年塔里木灌区气候分为冷、暖两个阶段,前为冷期,后为暖期。
Abstract:According to the date of temperature and precipitation in the Tarim irrigation area from January,1961 to December 1999,the climate of the Tarim irrigation area is analysed.The results show that the precipitation of the Tarim irrigation area for 40 years appears to be ascending (4.569mm/10 a),the precipitation in autumn appears to be descending (-3 451mm/10 a) and the mean annual temperature appears to be going up (0.065℃/10 a), especially in the later 1990′s.The warming trend in winter is more than the cooling trend in summer.For this reason, in terms of the limit of the end of 1970′s the climate of the Tarim irrigation area for 40 years might be divided into two stages,the former is a cold period,and the latter is a warm period.
