By collecting the ground observation data of 20 national automatic meteorological stations in Beijing from 1981 to 2020,and selecting 6 representative plain observation stations and 5 mountain observation stations,the annual average temperature,annual average maximum temperature,annual average minimum temperature and various temperature of all observation stations,mountain observation stations and plain observation stations are analyzed,by linear fitting method and Mann-Kendall method.The temporal and spatial variation characteristics of temperature in Beijing in the past nearly 40 years are studied to provide a basis for further research on the temperature change patterns in the Beijing area.
