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 socioeconomic development, infrastructures, regional status, history of disaster, history of urban planning and development, government policies, etc.展开更多

Therefore, the expression of the architectural appearance, and characters of underground building, as well as the integration between the building and its external environment constitute an important part in improving overall functional structure and optimizing cityscape. From the perspective of space and environment shaping, the author explores the architectural appearance, and characters of underground building and its external environment, provides several basic design patterns with further discussion.展开更多

文摘Underground building with such major functions as underground traffic, commerce, culture and recreation, especially the multifunctional underground large-scale public complex, has become a significant part of the overaU functional structure or even the core of a city. Therefore, the expression of the architectural appearance, and characters of underground building, as well as the integration between the building and its external environment constitute an important part in improving overall functional structure and optimizing cityscape.
