徐州市PM_(2.5)和PM_(10)相关性分析

Correlation Analysis of PM_(2.5) and PM_(10) in Xuzhou City

徐州市是典型的煤炭工业城市,目前,大气污染依然比较严重,颗粒物是影响区域大气质量改善的主要污染物。本文以徐州市为研究区,利用国控监测站、省控监测站获得的细颗粒物(PM_(2.5))、可吸入颗粒物(PM_(10))质量浓度数据,结合大气灰霾超级站在线监测数据,综合运用数理统计和相关性分析,探讨PM_(2.5)和PM_(10)的时间变化特征,明确二者的相关性。作为老工业基地,徐州市必须充分发挥资源优势和创新优势,大力发展新型能源和双碳产业,从而削减PM2.5和PM10的排放量,改善区域生态环境。

Xuzhou City is a typical coal industry city,currently,air pollution is still relatively serious,and particulate matter is the main pollutant affecting the improvement of regional air quality.Taking Xuzhou City as the research area,this paper uses the mass concentration data of fine particulate matter(PM_(2.5))and inhalable particulate matter(PM_(10))obtained from national and provincial monitoring stations,combined with the online monitoring data of the atmospheric haze super station,and comprehensively uses mathematical statistics and correlation analysis to explore the temporal variation characteristics of PM_(2.5) and PM_(10),clarifying the correlation between the two.As an old industrial base,Xuzhou City must fully leverage its resource and innovation advantages,vigorously develop new energy and dual carbon industries,thereby reducing PM_(2.5) and PM_(10) emissions and improving the regional ecological environment.
