摘要
为了解校园周围自由市场对校园大气质量的影响，选择常用的反映大气污染程度的４项指标对校园大气质量进行监测，根据监测数据对校园大气质量进行综合评价，结果表明，校园附近自由市场（主要指饭馆炉灶）对校园大气质量是有一定影响的，尤以飘尘的影响较为显著，各项监测指标的浓度均以清晨为最高。并提出了改善校园大气质量的建议。
n order to understand the influence of atmospheric quality
caused by the nearby freemarket over the college campus,4 indexes of monitoring were
selected and applied to mea-sure air polution. Based on the data obtained, comprehensive
evaluation was implemented aswell.The results indicated that the nearby free market,mainly
the cooking ranges of restau-rants,was of a certain influence to atmospheric quality especially
