摘要
以上海市2002年-2009年的PM10实测数据和同步气象资料为研究对象进行上海市PM10污染分析研究。对2002年-2009年的监测数据进行分析、归纳,得到了上海市可吸入颗粒物(PM10)浓度的季节变化规律、每日小时变化规律以及上海市不同地区可吸入颗粒物(PM10)浓度的分布特征,并对这种特征及变化规律进行了详尽地分析。研究表明上海市空气环境质量在逐年好转,其标志是累计超标污染天数每年减少5天;在一年当中,污染天数最多的是冬季,其次是春季,最少的是夏季;在空气环境质量逐年好转的大趋势下,针对其产生的原因进行了分析。
PM10 pollution analysis of Shanghai was conducted with PM10 measured data and synchronous meteorological data from 2002 to 2009 as research targets.The analysis and summary of monitoring data from Shanghai air automotive monitoring system during 2002-2009 concluded the seasonal,daily and every hour inhalable particulate matter concentration regularity and distribution characteristics of inhalable particulate matter concentrations in different parts of Shanghai.Detailed analysis of the characteristics and variation regularities enabled more accurate air quality forecast in Shanghai.Better mastery of Shanghai air pollution status provides support to air pollution prevention.Research results show that air environment quality improved year by year marked by annual average 5 days reduction of cumulative excessive pollution day.Most polluted days are in winter,followed by spring,and least in summer.This paper analyses the causes for yearly improvement of air environment quality.
