摘要
为了掌握宝鸡市大气环境质量现状,选取二氧化硫、二氧化氮和可吸入颗粒物三个污染因子作为评价指标,参照国家大气环境质量标准,对宝鸡市1996—2011年的大气环境质量进行分析和评价,并应用大气质量标识指数评价法对各评价指标及各年综合大气环境质量进行评价.结果表明:宝鸡市1996—2011各年三个污染因子中的可吸入颗粒物对环境的污染最严重,始终超出环境功能区的要求;宝鸡市大气环境总体质量正在逐步改善.大气质量标识指数法是可被科学、合理应用于大气环境质量评价.
In order to determine the status of air environment quality in Baoji City,three pollution factors SO2,NO2 and PM10 were selected as evaluation parameters to analyze and evaluate atmospheric environmental quality,and to evaluate each evaluation parameter and the annual integrated air environment quality using air quality identification index evaluation method in Baoji City from 1996 to 2011.The results show pollution of PM10 is the most serious in three pollution factors from 1996 to 2011,and always beyond the requirements of the environmental function area.Furthermore,the overall quality of atmospheric environment is gradually improving in Baoji City.Also proved that air quality identification index evaluation method is scientific and reasonable,used in air environment quality assessment.
