城市空气质量监控宏观模型

A Macro Model for Monitoring Urban Air Quality

选择PM 10作为测度空气质量的指标,以城市拥有公共交通工具数量和城市绿化覆盖率作为解释变量,通过线性回归建立基于全国各大城市截面数据模型,样本回归模型显示,城市的绿化面积和城市居民私家车拥有量与该城的废气处理能力存在着一定的线性关系。

Taking the number of urban public vehicles and afforestation coverage in the city as variables,the present paper selects PM 10 as the index for estimating air quality to build a model based on the cross-section data of national metropolitan cities,with the method of linear regression.The sample regression model shows that the urban green area and the number of private cars citizens possessing have a certain linear relation to the city’s capability of disposing waste gas.
