摘要: 为了研究柴达木盆地东南部气候变化趋势,笔者利用柴达木盆地东南部都兰县气象局观测的1961—2016年气温资料,使用线性倾向估计、滑动平均、M-K突变分析等方法,分析了都兰县1961—2016年气温的变化特征。结果表明:1961—2016年都兰县年平均最高气温、年平均气温、年平均最低气温均呈极显著升高趋势,其气候倾向率分别为0.33 ℃/10a、0.28 ℃/10a、0.24℃/10a。年极端最高气温以0.23℃/10a的气候倾向率呈显著升高趋势,年极端最低气温以0.17℃/10a的气候倾向率呈不显著升高趋势。突变分析表明,年极端最低气温、年平均最低气温、年平均气温和年极端最高气温、年平均最高气温分别在1966年、1979年、1985年和1990年发生了由低到高的突变。

Abstract: The paper aims to study the characteristics of temperature variation tendency in southeast of Tsaidam Basin. The authors used linear trend estimation method, moving average method and M-K abrupt analysis to analyze the temperature variation characteristics in southeast of Tsaidam Basin during 1961 to 2016. The results showed that the annual average maximum temperature, the annual average temperature, the annual average minimum temperature, were significantly elevated, the tendency rate of the above temperatures were 0.33℃/10a、0.28℃/10a、0.24℃/10a.The annual extreme maximum temperature was significantly elevated trend with 0.24℃/10a climate tendency rate, the annual extreme minimum temperature was not significant increase trend with 0.17℃/10a. The climate abrupt analysis shows that, The annual extreme minimum temperature 、the annual average minimum temperature 、the annual average temperature and the annual average maximum temperature , the annual extreme maximum temperature, respectively, had a from low to high climate abrupt in 1966,1979,1985 and 1990.
