Spatial and Temporal Distribution Characteristics of Heritage Buildings in Yangzhou and Influencing Factors and Tourism Development Strategies

Heritage buildings are significant humanistic tourism resources for a city. Yangzhou’s heritage buildings have conservation and utilization value and are a key vehicle for promoting urban tourism development. However, there is a lack of research on their spatiotemporal distribution characteristics and subdivision types. This study aims to explore the spatial and temporal clustering and distribution characteristics of Yangzhou’s heritage buildings, as well as the factors contributing to the formation of these distribution patterns, as a means of promoting the tourism development of Yangzhou. Using mathematical statistics and GIS spatial analysis methods, this study analyzes the geographical distribution patterns of 528 heritage buildings and their influencing factors by using average nearest neighbor analysis, an imbalance index, and density mapping. This study reveals the following findings: (1) The temporal distribution shows an “Λ” shape, in which ancient buildings, modern historical sites, and important modern historical sites and representative buildings account for a significant proportion. (2) The temporal center shows a trend of shifting over time, moving from the southwest to the northwest and then to the northeast. (3) The spatial distribution is uneven; most of these are clustered in Hanjiang District, Gaoyou District, and Baoying County, while few are distributed in other regions. (4) The distribution is influenced by both natural and human factors, including topography, water resources, salt merchant culture, revolutionary culture, war culture, and canal transportation culture, with humans and human factors having a more profound impact than natural factors. Based on these findings, strategies such as regional integration and route planning, the prioritization of sustainable tourism development and preservation, and culture fusion and innovative promotion are proposed in this study as references for the all-for-one tourism development and cultural dissemination of Yangzhou.
