摘　　要：对北方工业大学校园内几种建筑布局及其绿地中空气的PM2.5浓度所进行的调查表明,不同建筑布局会影响其PM2.5的浓度分布,而不同绿地形式也会对PM2.5浓度产生相应的影响,进一步地,建筑布局与绿地形式的不同结合也导致了PM2.5浓度的变化。调查还显示:①灰霾天气条件下,建筑群中空气的PM2.5浓度远超国家标准;②所调查的多种绿地均可在一定程度上降低空气的PM2.5浓度,但效果小于植物群落;③建筑布局的高度、围合方式对空气中PM2.5的浓度具有一定影响;④多层合院式布局中的林荫道能有效减少PM2.5浓度。居住区规划设计应当注意采取适当的布局,以利于减少PM2.5暴露。In this paper,the northern industrial university campus in several architectural layout and green space of PM2.5 survey shows that different architectural layout can affect the PM2.5 concentrations,and different forms of green space also can produce the corresponding influence,building layout and green space form of different combination also resulted in the change of PM2.5 concentrations.The survey also shows that：1） in the grey haze weather conditions,the buildings of PM2.5 concentrations far supranational standards; 2） green space in a certain extent,reducing PM2.5 concentrations,but the effect is less than the plant community; 3） the height of the architectural layout,enclosing way for PM2.5 has certain influence; 4） architecture and green space,and the different combination of PM2.5 concentration also can produce certain effect.Residential district planning and design should pay attention to take the appropriate layout,in order to reduce PM2.5 exposure.
