以上海市为例,运用定性与定量分析相结合的方法,分别从制造业郊区化和住宅郊区化两方面分析对上海城市发展的影响。结果表明:1制造业郊区化总体上改善了城市环境空气质量,但对中心城区和郊区的影响方向相反;2住宅郊区化加剧了中心城区和郊区的职住分离现象,恶化了中心城周边地区的交通拥堵状况;3制造业郊区化和住宅郊区化均在一定程度上造成了土地资源的过量消耗。因此,伴随上海郊区化进程的深化,既要控制和削减NO2和PM2.5的排放浓度,又要统筹推进产城融合发展;既要注重推进郊区土地的节约和集约利用,又要控制房价过快上涨,还要关注近郊区的人口结构、产业结构、用地结构、空间结构的互动调整和优化,力争将上海建设成为资源节约型、环境友好型、社会和谐型、生态宜居型的全球城市。
Taking Shanghai as an example, this paper uses qualitative and quantitative analysis methods to analyze the impact of Shanghai’s urban development from two aspects: manufacturing suburbanization and residential suburbanization. The results show that: 1) Suburbanization of manufacturing industry has generally improved the ambient air quality in urban areas, but has opposite impacts on the downtown and suburbs; 2 Suburbanization of housing has exacerbated the segregation of duties and work in the downtown area and suburbs, deteriorating the area around the central city Of the traffic congestion; 3 manufacturing suburbanization and residential suburbanization have to some extent caused the excessive consumption of land resources. Therefore, along with the deepening of suburbanization in Shanghai, it is necessary to control and reduce the emission concentrations of NO2 and PM2.5 and to co-ordinate the development of industrial and financial integration in the urban areas. We should not only pay attention to promoting the conservation and intensive use of land in the suburbs, But also pay close attention to the adjustment and optimization of population structure, industrial structure, land use structure and spatial structure in the suburbs, and strive to build Shanghai into a resource-saving, environment-friendly, socially harmonious and ecologically livable global city .
