Abstract: With rapid urbanization, air pollution has become an important problem threatening the health of urban residents. Urban green space and three-dimensional building configuration are core components of urban pattern, playing an important role in the dispersion of air pollutants. Here, we reviewed the influence of urban green space on the deposition, absorption, and dispersion of air pollutants, clarified the relationship between three-dimensional building configuration and air pollutants, and analyzed comprehensively regulation of urban green space and three-dimensional  building configuration on air pollutant. We suggested that future research should concentrate on the role of green space and three-dimensional building pattern on air pollutant concentration base on field investigation across urban street canyons, communities, city, and agglomeration scales, reveal the mechanism underlying air pollutant diffusion, and provide guidelines for urban green space management, urban planning, and architectural design to mitigate urban air pollution.

Key words: air quality, urban forest, particle, landscape pattern optimization, spatial planning.
