摘　　要：利用1981—2020年英吉沙国家一般气象站的年平均气温、年极端最高气温、极端最低气温、降水量等地面观测逐日数据,采用显著性检验法、趋势系数法和一元线性回归等方法,对英吉沙县逐年极端气温和最大日降水量的变化特征进行了分析,得出以下结论:1981—2020年英吉沙县年平均气温、年极端最高、最低气温均呈升高趋势,其年平均气温和年极端最高、最低气温气候倾向率分别为0.38℃/10 a、0.10℃/10 a、0.27℃/10 a,且年平均气温的上升率高于年极端最高气温、年极端最低气温。近40 a来英吉沙县年最大日降水量平均值为16.0 mm,最大值达42.1 mm,最小值仅有4.6 mm,说明该地区最大日降水量的年际变化幅度较大。This paper analyzes the variation characteristics of the annual extreme temperature and the maximum daily precipitation in Yingjisha County by using the daily observation data of the annual average temperature,the annual extreme maximum temperature,the extreme minimum temperature and the precipitation of the general meteorological station in Yingjisha from 1981 to 2020,and adopts the methods of significance test,trend coefficient and one-way linear regression,The following conclusions are drawn:the annual average temperature,annual extreme maximum temperature and lowest temperature in Yingjisha County are rising from 1981 to 2020.The annual average temperature and the annual extreme maximum and minimum temperature climate tendency rate are 0.38℃/10 a,0.10℃/10 a and 0.27℃/10 a respectively,and the annual average temperature rise rate is higher than the annual extreme maximum temperature and annual extreme minimum temperature.The average annual maximum daily precipitation in Yingjisha county is 16.0 mm,the maximum value is 42.1 mm and the minimum is only 4.6 mm in recent 40 years,which indicates that the annual variation range of the maximum daily precipitation in this area is large.
