Accurate Identification of Micro-scale Urban Functional Zones from the Perspective of Dialectical Materialism

With the advancement of global urbanization, accurate identification of urban functional zones has become a crucial task for the high-quality development of cities. Traditional methods that rely on POI data are insufficient to accurately identify micro-scale urban functional zones. Thus, this study proposes a novel method for identifying urban functional zones based on VOI (Volume of Interest) data and applies it to a small region in Hong Kong for comparative research. Subsequently, the identification accuracy of the two methods is assessed using a confusion matrix and the Kappa Coefficient. The results show that the VOI data contains richer and more comprehensive urban spatial information compared to POI data, which can represent superior connections and influences among different zones within cities. The study can be applied to analyse micro-scale urban functional zones in other cities, providing a fresh perspective for in-depth research.
