黑龙江省“十三五”环境空气质量变化情况及影响因素研究

Analysis on Changes and Influencing Factors of Ambient Air Quality in Heilongjiang Province During 13th Five-Year Plan

根据黑龙江省“十三五”期间黑龙江省和各地市六项主要大气污染物监测结果,结合已实施的大气污染防治任务,分析黑龙江省“十三五”环境空气质量变化情况及影响因素。“十三五”环境空气质量明显改善,达标天数比例呈上升趋势,PM2.5、PM10、SO2、NO2、CO、O3浓度值相对于2015年都有不同程度下降,目前PM2.5仍是首要污染物,重度以上污染全部发生在冬春季节。产业结构、能源结构、交通运输结构调整、重点污染源治理等措施为黑龙江省环境空气质量改善起到了重要作用。

According to the monitoring results of six major air pollutants in Heilongjiang Province and cities during the 13th Five-Year Plan period,this paper analyzes the changes and influencing factors of ambient air quality by combing with the implemented air pollution prevention and control tasks.The ambient air quality of Heilongjiang Province has improved significantly in the 13th Five Year Plan period,and the proportion of days reaching the standard is on the rise.The concentrations of PM2.5,PMl0,SO2,NO2,CO and O3 have decreased in varying degrees compared with 2015.At present,PM2.5 is still the primary pollutant,and all severe pollution occurs in winter and spring.Industrial structure,energy structure,transportation structure adjustment,key pollution source control and other measures have played an important role in improving air quality in Heilongjiang Province.
