摘要
快速城市化带来的空气污染严重影响城市居民生活,通过制定合理的城市规划策略可改善城市空气质量。文章基于城市形态对空气质量影响路径选取相关城市形态参数,通过实地监测与数值模拟构建全时空污染物分布预测模型,以双变量相关分析探究对PM2.5影响较大的形态参数,并在此基础上提出街区尺度空间环境的优化建议,可为中观尺度下居住街区内缓解空气污染、优化居住街区形态提供一定的参考价值。
The air pollution caused by rapid urbanization seriously affects the life of urban residents,and the urban air quality could be improved by formulating reasonable urban planning strategies.The study selected the urban form parameters based on the influence path of urban form on air quality.The real-time pollutant distribution prediction model was established by field monitoring and numerical simulation.The morphological parameters with great influence on PM2.5 were screened out by bivariate correlation analysis.On this basis,suggestions for optimizing the space environment at neighbourhoods scale were put forward.The results could provide some reference value for mitigating air pollution and optimizing the form of residential neighbourhoods at mesoscale.
