摘要
太原市作为重要能源和重工业基地,臭氧污染问题日益凸显,成为影响空气质量的主要因素。在此背景下,进行大气臭氧污染特征及气象因素分析。研究中采集气体样本并检测污染浓度。按照时间和空间两个维度,分析大气臭氧污染特征。以风速、温度和湿度三个气象条件为变量,分析对污染浓度的影响并计算浓度超标率。时间上,臭氧污染集中在夏季的午后至傍晚时段;空间上,臭氧污染集中在东部中心区域,包括尖草坪区、万柏林区、杏花岭区、迎泽区、小店区等。在风速3.0 m/s~5.5 m/s、高温、低湿的天气条件下,臭氧污染尤为严重。
As an important energy and heavy industry base,ozone pollution has become increasingly prominent in Taiyuan City,becoming the main factor affecting air quality.This paper analyzes the characteristics of atmospheric ozone pollution and meteorological factors by collecting gas samples and detecting pollution concentrations.The characteristics of atmospheric ozone pollution were analyzed from two dimensions of time and space.The paper analyzed the impact of three meteorological conditions,namely wind speed,temperature,and humidity,on pollution concentration and calculated the concentration exceedance rate.In terms of time,ozone pollution is concentrated in the afternoon to evening period of summer;In terms of space,ozone pollution is concentrated in the eastern central area,including the Jiancaoping District,Wanbailin District,Xinghualing District,Yingze District,Xiaodian District,etc.Ozone pollution is particularly severe in weather conditions with wind speeds ranging from 3.0 to 5.5 m/s,high temperatures,and low humidity.
