Abstract: Ventilation corridors are designed to relieve heat island effect, enhance ventilation and protect the land used for climatic and environmental enhancement in a city. Observations and analogs of ventilation corridors in typical regions show that ventilation corridors affect micro-climatic environment to a certain extent and help to reduce local heat island effect and increase local wind speed; but they contribute little to wind speed in a static or nearly static condition. Influenced by climate change and urbanization, China has been frequently blighted by large-scale smog in recent years. However, ventilation corridors cannot change the meteorological condition of large-scale air stagnation and other conditions against air diffusion. The best solution to air pollution is the emission control of pollution sources. Rational planning and construction of ventilation corridors, in the meantime, can be a supplementary measure for urban ecological and environmental improvement in a long run.
