中文摘要:
      通过对黑龙江省4个自然年(2016年1月1日—2019年12月31日)环境空气污染物和气象要素的分析,揭示了黑龙江省气象条件对空气污染物浓度的影响规律与特征。对PM2.5、PM10、SO2、NO2、CO和O3等6项污染物的描述性统计和简单的相关分析显示:黑龙江省环境空气质量呈现逐年变好的趋势,非采暖期环境空气质量好于采暖期,6项污染物中除O3呈现夏季偏高以外,其余污染物采暖期浓度均高于非采暖期。运用典型相关分析法探究环境空气污染物与温度、降水量、相对湿度、风速和气压5项气象要素之间的关系,并进行统计学检验,结果表明:环境空气污染物与气象要素之间存在显著相关,温度、风速和相对湿度对污染物具有显著影响。非采暖期大气相对湿度对PM10和O3-8h的影响显著;而在采暖期,风速对PM10和PM2.5的影响显著。
英文摘要:
      Based on the analysis of the ambient air pollution indexes and meteorological elements in the four natural years (from January 1,2016 to December 31,2019) of Heilongjiang Province,the influence law and characteristics of meteorological conditions on the air pollutant concentration in Heilongjiang Province were revealed in this paper. During the study period,the descriptive statistics and simple correlation analysis of PM2.5,PM10,SO2,NO2,CO and O3 showed that the ambient air quality in Heilongjiang Province improved year by year,and the ambient air quality in non-heating period was better than that in heating period. The concentration of six pollutants in heating period was higher than that in non-heating period except O3,which was higher in summer. Canonical correlation analysis was used to explore the relationship between ambient air pollutants and five meteorological elements,including temperature,rainfall,relative humidity,wind speed and air pressure,and then statistical test was conducted. The results showed that there was a significant correlation between ambient air pollutants and meteorological elements, and temperature, wind speed and relative humidity had a significant impact on the changes of pollutants. Among them, the relative humidity in the air during non-heating period had a significant impact on PM10and O3-8h, while in the heating period, the wind speed in the air had a significant impact on the pollutants PM10 and PM2.5.
