Mapping the character of urban districts: The morphology, land use and visual character of Chinatowns

This paper examines the urban character of Chinatown districts around the world, as a key example of an urban ethnic enclave, focusing on four large Chinatowns in San Francisco, Yokohama, Melbourne and Sydney. It advances knowledge about the spatial elements that define urban districts, a concept pioneered by Kevin Lynch. Existing literature on Chinatowns primarily explores the historically changing relationships between their Chinese migrant communities and their host cities, or the visual and physical character of individual cases. This paper develops new insights into how the built forms of these urban districts are similar to or different from their surroundings and from each other. It employs a methodology that combines space syntax analysis of street networks, morphological analysis of built form, land-use analysis, and mapping of visual character from street level. It examines the Chinatown districts' spatial extents in terms of contrasts between their spatial attributes and their wider urban surroundings. The findings develop a new taxonomy of Chinatowns based on their urban spatial characteristics.
