京津冀地區(qū)PM2.5和O3污染特征及潛在源研究

京津冀地區(qū)PM2.5和O3污染特征及潛在源研究摘要

本文針對京津冀地區(qū)PM2.5和O3污染進(jìn)行研究，基于2013年至2017年的觀測數(shù)據(jù)，對污染特征和潛在來源進(jìn)行探討。結(jié)果表明，京津冀地區(qū)PM2.5和O3污染程度較嚴(yán)重，且季節(jié)變化明顯。冬季PM2.5濃度最高，夏季O3濃度最高。污染物排放和局地形態(tài)對污染物濃度和分布具有重要影響，城市化和交通工具使用也是污染主要來源之一。針對這些問題，提出了可持續(xù)發(fā)展方案，包括減少排放、控制交通排放、提高工業(yè)生產(chǎn)效率和推廣新能源等措施。這些方案可以為京津冀地區(qū)的污染治理提供參考。

Introduction

Inrecentyears,airpollutionhasbecomeoneofthemajorenvironmentalproblemsintheBeijing-Tianjin-HebeiregionofChina.PM2.5andO3arethemainairpollutantsinthisregion,whichposeaseriousthreattohumanhealthandtheenvironment.Inthisstudy,weanalyzedthecharacteristicsandpotentialsourcesofPM2.5andO3pollutionintheBeijing-Tianjin-Hebeiregionbasedonobservationdatafrom2013to2017.

Methods

WecollectedandprocessedobservationaldataonPM2.5andO3concentrationfrom12monitoringstationsintheBeijing-Tianjin-Hebeiregion.Thedatawereanalyzedusingstatisticalmethods,includingcorrelationanalysis,principalcomponentanalysis,andtrajectoryanalysis.Wealsocombinedtheobservationdatawithsatelliteimageryandchemicaltransportmodelstoidentifythemainsourcesofpollution.
