摘    要:根据乐山大佛景区环境空气质量监测数据,分析了二氧化硫(SO2)、二氧化氮(NO2)、可吸入颗粒物(PM10)3种污染物的时间变化规律及污染特征.结果表明:乐山大佛景区环境空气质量相对较好,优良率在87%以上,可吸入颗粒物浓度值在低浓度水平的基础上有上升的变化趋势,达到现行国家环境空气质量标准,二氧化硫、二氧化氮的污染总体上变化不显著.

关 键 词:乐山大佛景区  环境空气  空气质量  变化规律  污染特征

Abstract:According to the ambient air quality monitoring data of the Leshan Giant Buddha, the time variation and pollution characteristics for 3 kinds of contaminants, sulfur dioxide ( SO2 ), nitrogen dioxide ( NO2 ) , and particulate matter (PM10) was analyzed. The results show, the ambient air quality for Leshan Giant Buddha is relatively good, and excellent rate is over 87%. On the basis of low concentration, the respirable PM(particulate matter) concentration index has an upward trend, reaching the current national ambient air quality standards, and no significant change for sulfur dioxide, nitrogen pollution.
Keywords:Leshan Giant Buddha  ambient air  air quality  variation  pollution characteristics
