This research aims to examine stakeholder participation and visualisation in China throughout the multi-scale planning process.

Beginning with the institutional analysis, it scrutinises the legal requirements and visualisation tools for stakeholder participation. The urban planning exhibition hall presents multi-scale planning information through various visualisation displays.

Evaluation of its role in information dissemination and stakeholder participation is carried out using a repeated measures design. The planning standards are intertwined with planning practices, with the emergence of two planning processes: top-down and bottom-up approaches.

Through follow-up case studies during initiation, planning and implementation phases, it seeks to unravel the interrelationship between planning scales, the interaction between stakeholders and the role of visualisation.



Understanding the role of views in homebuyers' choices with the help of visualisation in Guangzhou, China

When homebuyers make homes purchase decisions, a number of factors could influence their choices. This research aims to understand one of the influential factors - views from residential homes.

Questions are raised including which views homebuyers prefer, how much they are willing to pay and why they prefer these views. The research attempts to apply immersive visualisation simulation as a research tool to display views from high-rise apartments in Guangzhou and to unveil participants’ preferences.

By answering these research questions, it is expected that the research could provide implications for stakeholders such as planners, policymakers, developers, etc.


Modeling and analysis of urban green space accessibility in Guangzhou

Enough accesses to Urban Green Space (UGS) are crucial for human. However, there are few studies analyzing the perceived and actual UGS accessibility. Therefore, it is necessary to explore the comprehensive accessibility of UGS in urbanized Guangzhou from different aspects.

This research aims at modeling the spatial, the perceived and the close-to-reality accessibility of UGS in which are overlooked by previous researches Then it provides principles on the more reasonable plan of UGS.

For measuring the accessibility, it uses the two-step floating catchment area model in which coefficients will be obtained from questionnaires to get the theoretical accessibility. The perceived accessibility will be modeled via analyzing the data from survey. The close-to-reality accessibility will be modeled by space-time utility-based measure referring to previous studies. All the data used for analysis will be obtained by questionnaires and interviews.

This research proposes novel conceptual framework and modeling method for analyzing the UGS accessibility. The results can determine hidden factors affecting actual accessibility of PGS. It also indicates possible social inequity on accessing to UGS. It will also contribute to targeted suggestions on improving the UGS accessibility in prospective UGS design and plan

Study on the theory and methods of resilient delta planning and design and its application in Pearl River Delta

Natural disasters in the Pearl River Delta are more diverse, frequent, overlapping, uncertain and destructive than those in other regions. How to balance the protection of the natural basement with the needs of urban development becomes an important task for government, planning and design departments and research institutions in order to better adapt to climate change in the future.

The Ph.D. project systematically studies the theory and method of resilient planning and design for the delta area, and applies the research results of theory and method to the Pearl River Delta.

 Main contents and innovations in this project are as follows.

  1. Unique landscape of the delta area, existing situation of Pearl River Delta and the significance of resilience are studied.
  2. The theoretical framework of resilient planning and design for delta area is put forward, with “three capacity, four connotation and six spatial characters”.
  3. The methodological framework of resilient planning and design for the delta area is proposed, with a conceptual model of “thee-lines” and “five categories of space”.
  4. The conducting steps for resilient planning and design are put forward.
  5. The strategies and measurements of resilient planning and design for Pearl River Delta are suggested.
  6. The strategies of resilient planning and design for Nansha and Pearl Bay are respectively suggested.
