| Abstract: | Vulnerability is a new field and analytical tool in the study of urban safety. Analysis and assessment of vulnerability provide
a new basis for urban planning. This study constructed a quantitative index system for assessing vulnerability, based on the
city’s sensitivity and emergency response capacity. City size, density, and spatial form influence a city’s sensitivity to
crises and risks, to which vulnerability is positively related. Levels of socio-economic development, infrastructures, and
emergency management contribute to a city’s emergency response capacity, with which vulnerability is inversely associated.
Vulnerability of 19 large Chinese cities was assessed. Harbin and Shenzhen demonstrated the highest and lowest vulnerability
among 19 cities, while Beijing, Shanghai and Guangzhou ranked the 5th, the 9th and the 12th. Spatially, northern cities tended
to be more vulnerable than southern cities. And the differences in vulnerability among cities were explored based on cities’
physical geography conditions, level of socio-economic development, infrastructures, regional status, history of disaster,
history of urban planning and development, government policies, etc. |
