"Island Effect": A Study on Spatial Connections of Perforated Shrinkage in Metropolitan Areas―An Empirical Analysis of Qingshan District in Wuhan
Abstract
As urban development progresses, the complex phenomenon of city shrinkage increases. Perforated shrinkage is a leading pattern within Chinese cities. In this study, the Qingshan District in Wuhan (including its chemical industrial area) is considered as a representative case of a large metropolitan area experiencing perforated shrinkage. Through the use of methods such as spatial syntax, Point Of Interest (POI) analysis, and word frequency analysis , the study examines material and social spatial connections to verify the existence of an "island effect". The following results were obtained: 1) Analysis of the topological relationships within the Wuhan metropolitan development area and the interior regions of the Qingshan District reveals that Qingshan has low global and local integration values as well as choice metrics, indicating issues related to roadway accessibility and uneven distribution of transportation facilities. This leads to weak internal and external material spatial connections. Additional kernel density analysis of public facility POIs indicates poor and uneven infrastructure distribution in Qingshan. Additionally, questionnaire surveys and word frequency analysis suggest deficiencies in the area's external attractiveness and independent development at the policy level. These factors interact and contribute collectively to the island effect within Qingshan District. 2) Recognizing the similarities in the developmental background and policy frameworks between other domestic cities experiencing perforated shrinkage and the Qingshan District, this study infers that the island effect is a characteristic of metropolitan areas showing perforated shrinkage and is closely tied to institutional factors within Chinese urban areas. 3) The phenomenon of metropolitan perforated shrinkage and spatial connections have an interactive relationship, leading to the emergence of regional island effects. These island effects underscore the importance of coordinated internal development within the region, providing novel perspectives for managing urban shrinkage. For instance, cities should accelerate the development of transportation networks and construction of public spaces to avert feelings of isolation and closure at the spatial connection level, addressing the problem of unbalanced development with prompt promotion of policies emphasizing cooperation and talent attraction. This study's exploration and findings on the mechanisms and impacts of the isolation caused by perforated shrinkage highlight the urgency for better-coordinated development plans. This study presents innovative ways to address urban shrinkage aimed at improved urban infrastructural connectivity, equitable development, and resilient urban planning.
