摘　　要：对天峨县气象站1984-2013年降水量、年平均气温、季节降水、季节平均气温、月平均降水量、月平均气温、极端气温变化特征及不同年代降水、气温特征等进行统计分析。结果表明:天峨县近30a年际降水变化呈下降趋势,年际平均气温呈上升趋势,多年平均降水量为1339.3mm,多年平均气温为20.5℃。各季节、各月降水分布不均,气温呈明显的季节划分,夏季(6-8月)平均降水量最多,占全年平均降水量54%,冬季最少,占全年平均降水量5%,月平均降水量最高峰出现在6月;一年最热的月份是7月,极端最高气温变化不大,极端最低气温呈下降趋势。20世纪80年代中后期降水正常略少,90年代属于丰水期,进入21世纪后,降水量偏少,从20世纪80年代中后期一直到21世纪头十年气温呈上升趋势,第二个十年的头4年呈下降的趋势。Based on the analysis of annual precipitation, annual average temperature, seasonal precipitation, seasonal average temperature, average monthly rainfall, average temperature and extreme temperature from 1984 to 2013and characteristics of different characteristics in decades of Tiane, it is found out that： precipitation in tiane county is decreasing, annual average temperature is incrseasing, muhi-year average rainfall is 1339.3 mm, multi-year average temperature is 20.5 ℃. The seasonal and monthly precipitation distribution are uneven, the temperature shows obviously seasonal differences, the maximum average precipitation is in summer （June to August） , accounting for 54% of the annual average, the minimum is in winter, accounting for 5% of the annual average, the peak of monthly average precipitation is in June. The hottest month of multi-year average is July, extreme high temperatures is steady and extreme low temperatures are downtrend. There was a slight decline in precipitation during the mid-to-late 1980s, but in 1990s it experienced a abundant water period, after that in 21st century, the precipitation has been declining. From the mid-to-late 1980s to the first decade of the 21st century, temperatures were on the rise, and then turned into decline at first four years of the second decade.
