| 摘 要： | 利用MicrosoftExcel,对唐山市空气质量连续监测系统的一个点位全年数据进行日变化规律的统计分析。通过对各时段日变化规律的分析,得出①冬季燃煤量的增大不是影响PM10浓度变化的主要因素;②全年各时段燃煤量的变化是影响SO2的浓度变化的主要因素,因此消减潜力较大;③汽车保有量的快速增长对NO2浓度变化影响很大,同时对PM10浓度的变化也有一定影响。

| Abstract: | Taking Tangshan as an example and making use of Microsoft Excel, the paper introduces how to make data statistic and analysis of the law of daily change at a whole year's time points in the continuous monitoring system of air quality. By analyzing the law of daily variation at each time period, it includes: Firstly, the increase of coal consumption quantity in winter is not the key factor affecting the concentration of SO_2; Secondly, the variation of coal consumption quantity at each time period of a whole year is the dominant factor affecting the concentration of SO_2, so it has much potential in quantity decrease; Thirdly, the rapid increase of automobiles' conservative quantity has great effect to NO_2 concentration, the variation of PM_~10 concentration is affected as well. |
