jaue2021-038: Construction of Reduced-Type Urban Ventilation Corridor System under Epidemic Prevention and Control : A Case Study of Coastal Cities

Abstract

Since the outbreak of COVID-19, it has been realized that the environment with high density and high aggregation
in coastal cities has a natural disadvantage for the spread of viruses. Therefore, it is important to consider how to
alleviate the spread of viruses based on urban planning perspective in high-aggregation and high-density urban
environments. Most studies have planned and constructed a multi-scale epidemic prevention system from the
perspective of limiting people's flow. Due to the difficulty in controlling the virus, however, few people have studied
the methods to slow down virus transmission from the perspective of controlling the virus flow. In view of the fact
that urban ventilation facilitates the dispersion of Aerosol particles and that plants have the ability to adsorb Aerosol
particles, it was constructed that a reduced-type urban ventilation corridor system oriented to slow down the spread
of virus, through the planning and design of plant layout, building density and building height. The construction of
the corridor system can reduce the risk of human infection in unperceived or unreliable crowd infection, alleviate
the pressure of virus transmission in the high-aggregation and high-density urban environments in coastal areas and
provide an additional level of protection for people's health.
