【摘要】 利用2000—2008年环境监测数据,研究了福建省环境空气质量变化趋势及其影响因素.结果表明:从年际变化看,可吸入颗粒物的浓度呈下降趋势,二氧化氮基本稳定,二氧化硫浓度在低水平上呈上升趋势,但2008年略有下降;年内变化显示,冬、春两季污染较重,秋季次之,夏季污染相对较轻;从空间分布看,内陆城市空气污染程度重于沿海城市,大城市空气质量面临煤烟型污染和机动车排气污染的双重压力.污染减排、重点污染源的整治、能源结构的调整、清洁能源的使用等对空气污染防治、改善环境质量起到积极作用.更多还原

【Abstract】 Affecting factors and variation trends of air quality in Fujian Province is studied based on the environmental monitoring data during 2000 and 2008,showing that the concentration of inhalable particles was decreased,that of NO2 kept steady,and that of SO2 increased from a relatively low level but in the year of 2008 saw a small decrease.The result also indicates that the pollution was more serious in winter and spring seasons than in autumn,and the situation in summer was usually best.As for spatial distribution,the air pollution in inland cities was more serious than in coastal ones.And the big cities have to deal with coal-burning caused pollution and vehicle exhausts pollution.更多还原
