Reflections on New Urbanism at the COVID-19 Pandemic Background—Urban Health Research

The theory of New Urbanism, which promotes high-density, mixed zoning, and high walkable communities, has had a profound influence on the design of many cities globally and played a certain positive role in urban health. However, under the current COVID-19 pandemic, this theory faces new challenges. This paper aims to analyze the influence of New Urbanism on urban health from different spacial scales and reflect on whether these design methods still apply to the post-pandemic era. A series of recommendations for urban systems at different levels are proposed for further improving health of cities and residents. A real-world scenario-based design case is used to demonstrate ideas for optimizing public spaces in the districts. This paper is expected to provide ideas for future urban development and renewal design leading to a healthier and more sustainable city.
