Urban Design Study of Resilient City in Guangdong-Hong Kong-Macao Greater Bay Area

This abstract has open access
Abstract Summary
With the increasing climate change, the contradiction between the fragile hydrogeological conditions and the rapid urbanization process in the Guangdong-Hong Kong-Macao Greater Bay Area becomes much more prominent. As the result, the urban security is facing the severe challenge of natural disasters, such as sea level rise, frequent storm surges and intensified floods, etc. In order to solve this problem, this paper constructed the framework based on the research of the theory on resilient city, and analyzed the complex life cycles, as well as mutual synergy between different urban systems in Guangdong-Hong Kong-Macao Greater Bay Area. Besides, the urban zones which are easily affected by natural disasters in the Greater Bay Area were deduced in this paper, for the resilient urban planning methods are urgently needed in these zones; On the basis of the research, three major design principles were put forward: 1) multiple and diverse urban infrastructures; 2) redundancy and multi-dimensional, cross-scale networks; 3) the capabilities to self-organize, adapt, learn and update when facing interferences. These principles were applied to the urban planning and design practice of the middle and eastern Pazhou, Guangzhou, In this practice, resilient planning was explored through the diversified designs by the simulations of urban green infrastructure, through the refined designs of blue-green network to establish contacts with other parts of the city, and through the reasonabledesigns of mixing use of land functions and compact and high density construction to realize the renewal and flexible development of the city blocks. Practical experience shows that the realization of resilient city requires the comprehensive support from research to detailed design. Eco-oriented design can better coordinate the relationship between natural ecosystem and urban artificial system, and the dynamic renewal planning can endow the city with stronger resilience. This research attempted to make up for the lack of current study on resilient city in the field of planning and design practice, and provided a practical reference for the next stage of urban development.
