摘要: 近年来, 空气污染已成为限制西安城市人居环境质量提升的重要因素之一。当地政府采取了一系列的措施 进行空气污染治理, 其中机动车限行政策以其可实施性强、公共投入较少、简单易行等特点而最受青睐。在分析2016 ―2020 年间西安市空气质量变化趋势的基础上, 运用R语言针对相关影响因子 (限行政策、平均风速、相对湿度和平均 温度) 与空气质量之间的关系建立了广义相加模型, 并进行了拟合分析和相关性检验, 结果表明机动车限行政策与西 安市空气质量改善具有较明显的相关性。

Abstract: In recent years, air pollution has become one of the important factors limiting the improvement of urban living environment quality in Xi'an City, China. The local government has taken a series of measures to control air pollution, among which the motor vehicle restriction policy is most favored due to its strong feasibility, less public investment and simple operation. Based on the analysis of the trend of air quality changes in Xi'an from 2016 to 2020, R language is used to establish a generalized additive model for the relationship between relevant influencing factors (motor vehicle restriction policy, average wind speed, relative humidity and average temperature) and air quality, and then fitting analysis and correlation test are carried out. The results show that there is a significant correlation between vehicle restriction policy and air quality improvement in Xi'an City.

Key words: restricted traffic, motor vehicles, air quality, Xi'an City
