Using public perceptions to inform urban protected area buffer zone planning

The buffer zones between urban protected areas (UPAs) and their cities play a significant role in managing and protecting UPAs. However, they are also the frontier of conflicts due to complex functionality and a large number of stakeholders. Besides ensuring the buffer zone’s function of protecting the UPA, it is also vital to understand how it can fulfill the diverse needs of multiple interest groups residing in or utilizing this area. To address the significant social science research gap in UPA buffer zone management, we establish a conceptual framework and explore how the public’s overall satisfaction with the buffer depends on five essential buffer zone qualities, namely environmental quality, connectivity, infrastructure, cultural, and visual quality. We focus on China’s Urban Scenic and Historic Areas (USHA), a major type of UPA with high cultural, social, and esthetic values. Using the buffer of Shugang-Slender West Lake Scenic and Historic Area in Yangzhou City as the case study, we conducted intercept and online surveys (n = 499), investigating the perceptions of three user groups—residents, businesses, and tourists. The results indicate high overall satisfaction for all three groups. Environmental, visual, and cultural qualities were rated higher than connectivity and infrastructure quality. Residents generally showed the highest satisfaction and tourists the lowest. For all three groups, environmental quality, connectivity, and infrastructure quality significantly influenced overall satisfaction, while cultural and visual quality did not. This suggests that the public expects the buffer zone to serve as high-quality multi-functional open spaces that enhance the quality of life while providing recreation, service, and transportation functions. Besides direct planning and management advice to China’s UPAs and other countries with similar contexts, our study offers a transferable framework for incorporating social perceptions and highlights their significance in informing the functional planning of UPA buffer zones for public welfare.
