| 摘要: |
| 利用黔西南州8个国家气象观测站1961～2020年的极端最高、最低和平均最高、最低气温资料，以年代为周期，分析近60年黔西南州极端最高、最低和平均最高、最低气温的时空演变特征。结果表明：夏季，北亚热带季风湿润气候区及南亚热带季风湿润气候区的平均最高气温、平均极端最高气温在60年代至80年代处于持续上升趋势，在90年代略下滑，进入21世纪后又持续上升。北亚热带季风湿润气候区，近60年平均最高气温升高0.96℃，平均极端最高气温升高0.43℃；南亚热带季风湿润气候区近60年平均最高气温升高0.73℃，平均极端最高气温升高0.62℃。冬季，北亚热带季风湿润气候区平均最低气温及平均极端最低气温在70年代至80年代处于持续上升趋势，90年代略下滑，而进入21世纪又转为上升，近60年平均最低气温升高0.92℃，平均极端最低气温升高1.64℃；南亚热带季风湿润气候区，冬季平均最低气温及平均极端最低气温近60年呈持续上升趋势，平均最低气温升高2.35℃，平均极端最低气温升高3.32℃。 |

| Abstract: |
| Based on the data of extreme maximum, minimum, average maximum and minimum temperatures from 8 national meteorological stations in Qianxinan Prefecture from 1961 to 2020, the temporal and spatial evolution characteristics of extreme maximum, minimum, average maximum and minimum temperatures in Qianxinan Prefecture in recent 60 years were analyzed under one year a cycle. The results show that: In summer, the average maximum temperature and the average extreme maximum temperature in the north subtropical monsoon humid climate region and the south subtropical monsoon humid climate region are in a continuous upward trend from the 1960s to the 1980s, and slightly decline in the 1990s, and continue to rise after entering the 21st century. In the north subtropical monsoon humid climate zone, the average maximum temperature increased by 0.96 ℃ and the average extreme maximum temperature increased by 0.43 ℃ in recent 60 years; in the humid monsoon climate region of South Asia, the average maximum temperature increased by 0.73 and the average extreme maximum temperature increased by 0.62 ℃ in recent 60 years. In winter, the average minimum temperature and the average extreme minimum temperature in the subtropical monsoon humid climate region continued to rise from the 1970s to the 1980s, declined slightly in the 1990s, and turned to rise again in the 21st century. In the past 60 years, the average minimum temperature has increased by 0.92 ℃ and the average extreme minimum temperature has increased by 1.64 ℃; in the humid monsoon climate zone of South Subtropical Zone, the average minimum temperature and the average extreme minimum temperature in winter have been increasing continuously in recent 60 years, with the average minimum temperature increasing by 2.35 ℃ and the average extreme minimum temperature increasing by 3.32 ℃. |
