哈尔滨市空气重污染天气统计特征分析

Analysis of Statistical Characteristics of Air Heavy Pollution Weather in Harbin

通过对2013-2016年哈尔滨市空气重污染天气分析,从重污染天气过程的持续时间、平均浓度、小时浓度最大值、极差、标准方差及PM2.5与PM10的占比、SO2与PM2.5相关系数、NO2与PM2.5相关系数、CO与PM2.5相关系数等统计特征进行了计算,得出了哈尔滨市空气重污染过程具有持续时间长、污染重、以PM2.5为首要污染物以及燃煤型等重要的特征。

Based on the analysis of air heavy pollution weather in Harbin from 2013 to 2016,the statistical characteristics of duration,average concentration,maximum hourly concentration,extreme difference,standard variance,proportion of PM2.5 and PM10,correlation coefficient between SO2 and PM2.5,correlation coefficient between NO2 and PM2.5,and correlation coefficient between CO and PM2.5 were calculated,and the results showed that air pollution in Harbin had such important characteristics as long duration,heavy pollution,PM2.5 as the main pollutant and coal-burning type.
