摘要: 为了研究全球变暖大背景下宜宾地区的气温变化特征，本文利用宜宾站1960~2019年逐月的平均气温、平均最低气温、平均最高气温资料，用线性趋势法和M-K检验，研究了宜宾近60a气温的变化特征。得到了如下结论：近60a宜宾平均气温为18.0℃，平均最低气温为15.4℃，平均最高气温为21.9℃，气温变化均呈现显著增长的趋势，年平均气温增长率约为0.15℃/10a，年平均最低气温增长率约为0.20℃/10a，年平均最高气温增长率约为0.15℃/10a。宜宾年平均气温的增暖突变是从1998年开始的，突变前后气温增幅为0.7℃；年平均最低气温的增暖突变是从1994年开始的，突变前后气温增幅为0.6℃；年平均最高气温的增暖突变是从2004年开始的，突变前后气温增幅为0.8℃。
Abstract: In order to study the characteristics of temperature change in Yibin region under the background of global warming, the monthly mean temperature, mean minimum temperature, mean maximum temperature data from Yibin station from 1960 to 2019 were used to analyze the various characteristics of temperature in Yibin in recent 60 years by linear trend analysis and M-K test. The results show that the average temperature of Yibin from 1960 to 2019 was 18.0˚C, the average minimum temperature was 15.4˚C, and the average maximum temperature was 21.9˚C, and all the changes in the last 60 years showed a significant growth trend, the annual average temperature growth rate was about 0.15˚C/10a, the annual average minimum temperature growth rate was about 0.20˚C/10a, and the annual average maximum temperature growth rate was about 0.15˚C/10a. The abrupt change of annual mean temperature in Yibin began in 1998, and the temperature increased by 0.7˚C before and after the abrupt change. The abrupt change of annual average minimum temperature began in 1994, and the temperature increased by 0.6˚C before and after the abrupt change. The abrupt change of annual average maximum temperature began in 2004, and the temperature increased by 0.8˚C before and after the abrupt change.
