摘　　要：利用线性倾向率、M-K突变检验等方法,分析富宁县1957—2022年气温和降水变化特征。结果表明,近66年富宁县年平均最高气温、年平均气温、年平均最低气温、极端最高气温和极端最低气温均呈显著升高趋势,其中平均最高气温增高主要受夏季增温影响,平均气温增高主要受秋季增温影响,平均最低气温增高主要受冬季增温影响。年降水量减少趋势不显著,春季、夏季、秋季降水量表现为略下降趋势,冬季降水量和日最大降水量略增加,趋势均不显著。突变检验结果表明,年平均最高气温、极端最高气温、极端最低气温和年降水量的突变点分别在2013、2009、2000和1986年,而年平均气温、年平均最低气温和日最大降水量没有明显突变。Using linear trend rate,M-K abrupt change test,etc.,the change characteristics of temperature and precipitation in Funing County from 1957 to 2022 were analyzed.The results showed that the annual maximum temperature,annual mean temperature,annual minimum temperature,extreme maximum temperature and extreme minimum temperature in Funing County had all shown significant increasing trends in the past 66 years.Among them,the average maximum temperature had increased mainly due to the increase in summer temperature,the average mean temperature had increased mainly due to the increase in autumn temperature,while the average minimum temperature had increased mainly due to the increase in winter temperature.The trend of annual precipitation was not significant,and the precipitation in spring,summer and autumn showed a slightly decreasing trend,while the precipitation in winter and the daily maximum precipitation showed a slightly increasing trend,and the trend was not significant.The abrupt change test results showed that the annual maximum temperature,extreme maximum temperature,extreme minimum temperature and annual precipitation had undergone abrupt changes in 2013,2009,2000 and 1986 respectively,while the annual mean temperature,annual minimum temperature and daily maximum precipitation had not shown obvious abrupt changes.
