中文摘要：

冬季,北京市雾霾天气尤其严重,直观上与冬季供暖燃煤量增加不无关系。尝试在函数型数据视角下,将冬季供暖对空气质量的影响效应作量化分析。首先,通过二氧化硫（SO_2）浓度的日变动曲线,将供暖季与非供暖季作比较,得到冬季供暖的逐点微观影响效应;然后,通过描绘二氧化硫浓度的周变动曲线,得到供暖季二氧化硫浓度昼夜整体偏高,非供暖季二氧化硫浓度呈现周期波动,冬季供暖改变了二氧化硫浓度的周期变化规律。

英文摘要：

In winter,haze weather in Beijing is particularly serious,intuitively,which is related to the winter heating increase on the amount of coal. In the perspective of functional data,attempts were made to calculate the effect of heating in winter on the air quality. Through the daily concentration change curve,sulfur dioxide（SO_2）concentrations in heating season and non-heating season were compared to obtain pointwise microscopic effects of heating in winter. The weekly change curve of sulfur dioxide concentration showed high concentrations in the heating season and cyclical fluctuations in non-heating season,and the winter heating changes the periodic change of the concentration of sulfur dioxide.
