不同气象因子对北京城市铺装材料滞尘能力的影响
The influence of different meteorological factors on the dust retention capacity of urban pavement materials in Beijing
摘要
Abstract
Urban roads,rooftops,and other surfaces play an important role in blocking and accumulating particulate matters such as dust.However,as a common type of rough surface composed of paving materials,research on its dust retention effect has not been reported.An outdoor control experiment was adopted in this paper to quantitatively explore the dust retention changes of six common paving materials in Beijing in winter(December)and summer(June)and their interaction with meteorological factors.The results showed that the dust retention effects of different types of paving materials varied significantly in different seasons.In winter in Beijing,blocky(gravel,volcanic stone)and spherical(2 cm ceramsite and 3 cm ceramsite)paving materials could achieve better dust retention effects.Regression analysis showed that wind speed had the greatest negative contribution to the dust retention amount of blocky and flaky(wood chips,pine bark)materials,with contribution rates of-0.760 and-0.722;it had the greatest positive contribution to the dust retention amount of spherical materials,with a contribution rate of 0.717,being the dominant factor affecting the dust retention capacity of paving materials.In summer in Beijing,flaky paving materials could achieve better dust retention effects.Among them,humidity and rainfall had the greatest positive and negative contributions to the dust retention amount of all materials,with contribution rates ranging from 0.239 to 0.375 and from-0.857 to-0.925.关键词
