    摘要: 最近,雾霾天气在各大城市多发,对人体健康产生了极大危害,PM2.5等极细颗粒物作为雾霾天气产生的主因,备受关注。本文以山东某24层高公寓为研究对象,对不同公寓楼层高度迎风面与背风面楼道两侧以及不同室内通风条件下PM2.5浓度分布进行了检测,同时对室内各类活动因素(吸烟、烹饪、喷空气清新剂等)对PM2.5浓度变化的影响做了详细分析。研究表明楼道两侧迎风面与背风面PM2.5浓度分布受环境风场影响较大,低速和涡旋区不利于PM2.5扩散;室内空调系统有利于减弱PM2.5的影响。另外,室内各类活动对PM2.5浓度的影响具有过程性,其浓度随活动过程变化较为明显。Recently, the fog haze weather happened in lots of cities, which had a great harm to people’s health. PM2.5 and other finer particulate matters caught people’s attention as the main reason of causing fog haze weather. In this pa-per, a series of measurements were conducted on PM2.5 distribution inside and outside of one high-rise building in Shandong. The testing work of the PM2.5 concentration distributions inside of passageway in different height, and the effect of indoor ventilation and several housework on PM2.5 distribution had been done. It was found that the environ-ment wind fields had a great influence on the concentration distribution of PM2.5. In addition, the concentration of PM2.5 had a great change with the process of indoor activities.
