交通与气象因子对空气质量的影响研究

Study on Influence of Traffic and Meteorological Factors on Air Quality

目前中国存在经济生态发展不平衡,不可持续发展问题突出,多阶段、多领域、多类型生态环境问题交织。基于国家政策宏观调控下,展开交通与气象因子对空气质量的影响的深度研究。根据空气质量实时变化的数据,提出影响城市空气质量因素猜想,基于Lasso回归模型,对实证进行分析,经过BOOTSTRAP模型二次验证后,对空气质量影响较为显著的因素有:车流数量、风速、地面上层与下层温差。最后通过针对性提出绿色道路设计、互联网+新能源汽车、实时排污预警系统构建、城市空间合理布局四个方面,实现空气质量水平提升。

At present, China’s economic and ecological development is unbalanced. The problem of unsustainable development is prominent, and the problems of multi-stage, multi-field and multi-type ecological environment are intertwined. Based on the macro-control of national policies, the article uses this as an entry point to develop an in-depth study of the impact of traffic and meteorological factors on air quality. According to the data of real-time changes in air quality, the conjectures of urban air quality factors are proposed. Then, based on the Lasso regression model, the empirical analysis of conjectures, after the second verification by BOOTSTRAP model, the factors that have significant impact on air quality are:number of traffic, wind speed The temperature difference between the upper and lower floors of the ground. Finally, through the targeted introduction of green road design, Internet + new energy vehicles, real-time sewage early warning system construction, and reasonable layout of urban space, the air quality level will be improved.
