摘要
对城市道路大气中粉尘浓度的季节变化、日变化、道路平面横向变化、道路立面纵向变化等时空变异规律进行综述和分析,将道路大气中粉尘浓度时空变异的原因归纳为季候变化、天气变化、街道特征变化、道路级别与方位变化和交通流量变化,并提出了基于大气中粉尘浓度时空变异的滞尘植物配置。
The spatio-temporal variation rules of seasonal and diurnal variation,lateral plane variation and longitudinal elevation variation of atmospheric dust concentration in urban road were summarized and anylazed.The reasons of spatio-temporal variation of atmospheric dust concentration were come down to changes of season,weather,road characteristic,road class and direction,magnitude of traffic flow.And it was come up with the dust-retention plant design according to the spatio-temporal variation rules of atmospheric dust concentration.
