基于绿化景观总体布局的城市颗粒物空气污染消减系统研究

Urban Particulate Air Pollution Reduction System Based on Overall Green Landscape Layout

以城市的空间分布于行政区域划分为基础,搭建城市空间分布模型。在该模型下分析城市的景观绿地分布特点和城市的空气污染情况,并分析绿地与颗粒物消减之间的关系。最终通过设置消减率约束条件,实现城市景观绿地布局。通过对比实验分析得出结论与传统方法相比,该方法能够将城市内的颗粒物浓度控制在28.1 mg/m^3,即颗粒物空气污染的消减率提升了22.3%,由此证明了该方法的应用效果。

Based on the division of urban spatial distribution in administrative areas,the urban spatial distribution model is built.In this model,the distribution characteristics of urban landscape green space and air pollution are analyzed,and the relationship between green space and particle reduction is analyzed.Based on the analysis of the relationship between the reduction and the spatial distribution of the city.Finally,by setting the constraint conditions of reduction rate,the layout of urban landscape green space is realized.Compared with the traditional method,the method can control the concentration of particulate matter in the city at 28.1 mg/m^3,that is,the reduction rate of particulate air pollution is increased by 22.3%,which proves the application effect of the method.
