And the supply-side of the tourism remains very important. The RBD (Recreation Business District) is a useful framework to understand the components of urban tourism and how they fit together. The paper begins with a review on the RBD and the spatial structure of tourism in urban areas and then attempts to develop a more general understanding of the spatial structure evolution of RBDs in a tourist-historic city-Suzhou. The spatial structures and functions of the RBDs in Suzhou are examined, based on field observations, interviews with city officials and industry leaders, and a review of available documents. The urban tourism of Suzhou has developed in a range of contexts, that various types of RBDs have emerged as a result of different urban development strategies. The spatial structure has evolved from the past "Single-cored Structure" to "Double-cored Structure" at present, and then to "Chain Structure" in the future. The spatial form and evolution of RBD in Suzhou are closely relative with its urban spatial expansion. Urban area dispersal is the prerequisite of the emergence of the RBD. Planning and constructing the RBD becomes a new impetus to urban growth or renewal. Finally, a number of strategies for planning and developing the RBD in Suzhou are suggested. The different RBDs should adopt different strategies. Intensification can be the possible strategy for the RBDs in the ancient city. Accreting with the urban theme park or engrafting on the Jinji Lake is suggested respectively for the RBD in the Suzhou New District and the Suzhou Industrial Park.展开更多

Under the impact of the Internet virtual space on the urban physical space, however, the development of the physical commercial space in most cities of China is on a downward trend. Sino-Ocean Taikoo Li Chengdu has successfully broken out of this competition and became a research sample of the urban RBD. This paper is based on the integration of Sino-Ocean Taikoo Li Chengdu Project, including the concern for "place making", the integration of resources and the creative development and utilization of urban public space to explore the integrated design strategy of urban recreational space and commercial space for sustainable development.展开更多

In this paper, a fire risk assessment index system is established from the perspective of regional characteristics, possible sources and factors which influence the occurrence of fire. Analytic hierarchy process(AHP)is used to obtain the weights of different indexes so as to reflect their effects on the final fire risk assessment. Then, the fire risk of CBD in Binhai New Area of Tianjin is assessed with the help of the proposed model and Arc GIS technique. Finally, the fire station layout is optimized based on the discrete location model, realizing the reasonable allocation of firefighting resources. According to the analysis, super high-rise buildings and underground spaces are main factors that cause high fire risk; furthermore, five firstlevel fire stations can satisfy the requirement of rescue response time.展开更多
