摘　　要：目的北京市作为人口超过两千万的特大城市,人类活动对城市小气候的影响显著。以2019年北京市16个市辖区的逐日气温数据作为分析对象,探讨人类活动与城市气候之间的内在联系。方法通过连续小波变换和带通滤波方法对2019年北京市16个市辖区的气温日较差数据进行时序分析,捕捉蕴藏在季节周期和月周期内的受人类活动影响显著的周末效应。结果与结论北京市16个市辖区的气温变化存在明显的周末效应现象,其中以气温日较差数据序列的周末效应最为显著。周末效应是城市气候对人类生产和生活节奏周期性变化规律的宏观响应,其利弊性应该引起人们的关注。Purposes—To explore internal relationship between human activities and urban climate with the daily average air temperature data of the 16 districts in Beijing in 2019 as the subject of analysis for the urban climate of Beijing as a megacity with more than 20 million people is influenced significantly by human activities.Methods—The continuous wavelet transform and band-pass filtering methods were used to analyze the diurnal temperature range data of 16 municipal districts in Beijing in 2019 to capture the weekend effect of human activities within the seasonal and monthly cycles.Results and Conclusions—There is an obvious weekend effect phenomenon in the temperature changes of the 16 municipal districts in Beijing,and the weekend effect of the diurnal temperature range data series is of the most significance.Weekend effect is an overall response of urban climate to the cyclical changes of human life and productive activities,hence it should attract people's concern.
