石河子环境空气质量现状及污染成因分析

Analysis of Environmental Air Quality Status and Pollution Causes in Shihezi

石河子市工业布局较为集中,单位面积污染排放总量较大,并且八师石河子市所处天山北坡地带,冬季长时间受静稳天气条件控制,污染物扩散条件较差,出现大气重污染过程,影响范围广、污染程度重,对环境空气和人体健康造成明显影响。以石河子市环境空气为研究对象,根据石河子环境空气质量范围,监测结果发现:环境空气质量的污染现状、污染特征、变化趋势和污染物来源等因素密切相关,现以2020年至2021年1月-12月时间段空气质量历史监测数据进行了环境空气质量现状及污染成因的调查分析,并得到了环境空气质量的结论。

Shihezi's industrial layout is relatively concentrated,and the total amount of pollution emission per unit area is large.Moreover,Eighth Division Shihezi City is located in the north slope of Tianshan Mountain.In winter,it is controlled by static and stable weather conditions for a long time,and the pollutant diffusion conditions are poor.There is a process of heavy air pollution,which has a wide range of influence and heavy pollution degree,and has a significant impact on the ambient air and human health.Taking the ambient air of Shihezi City as the research object,according to the scope of ambient air quality in Shihezi,the monitoring results show that the pollution status,pollution characteristics,change trend of ambient air quality and pollutant sources are closely related.Now,the historical monitoring data of air quality from January to December 2020 are investigated and analyzed,and the countermeasures and suggestions are put forward.
