Analysis Of the Evolution of Urban Form in Modern Hefei City and Its Dynamics Mechanism

Abstract

As the capital of Anhui Province and the sub-center of the Yangtze River Delta urban agglomeration, Hefei has been increasing its regional status in recent years, and the city's spatial planning has gradually matured and becomes unique. This paper takes Hefei city as an example to explore the process of urban morphological evolution and its dynamic mechanism, describe the unique fan-type morphology of the city, and discuss the key factors and laws of its spatial and morphological development. Results show that Hefei was mainly a "doughnut-shaped" city before the founding of the People's Republic of China. After its founding, Hefei gradually formed a "fan-shaped" urban, extending to the present. The "fan-shaped" urban form can be subdivided into three modes: one-center with three-fan, one-center with multiple-cluster, and double-center with multi-cluster. In terms of the dynamics of urban form, modern urban planning theory lays the foundation of spatial form development, industrial development is the main driving force of spatial form development, and the economic system is the way to regulate spatial form development. The current spatial form pattern of Hefei is the result of the interaction of these factors.
