Research Review and Response Framework in Urban Planning for Air Pollution in Urban Street Canyons
分析了城市街道峡谷空气污染的现状、趋势和问题，基于公共安全生命周期理论提出污染源控制、扩散路径优化和受体保护的策略，并构建了包含污染机理、风险预警、规划设计等的研究框架，为城市规划提供参考。
The paper analyzes current situation,trend and existent problem of air pollution in urban street canyons.Due to the content and structure of scientific research,some solution strategies and future research contents are presented to prevent air pollution in urban street canyons.According to the Life-cycle theory of public safety management,solving strategies are established: pollution sources control,diffusion path optimization and pollution receptor protection.And then,scientific research framework which is consisted of street canyons pollution mechanisms,risk warning and preventing model,planning design and management,and information support platform is generalized.With the increasingly serious problems in China's urban environment and public safety,the paper proposes some urban planning strategies for preventing air pollution in urban street canyons,which can be used to solve the significant problems in the critical field of urban problems.
