Abstract

With the progress of urbanization, environmental challenges stemming from rapid urban sprawl have become pervasive. Consequently, research on urban sprawl has emerged as a crucial focal point in sustainable development efforts, emphasizing the need to understand the evolution characteristics and systemic mechanism of urban sprawl. However, existing research on the urban sprawl mechanism remains somewhat fragmented, lacking a unified research framework and theoretical model. In response, this paper proposes a theoretical framework for urban sprawl mechanics and constructs a unified analysis framework and an integrated urban sprawl force model. Furthermore, empirical analysis is conducted using Nanjing, Wuxi, and Yangzhou as case studies, measuring the integrated urban sprawl force and analyzing their urban sprawl characteristics through comparative assessments of the integrated urban sprawl force trends. The findings reveal distinct trends in the integrated urban sprawl force across Nanjing, Wuxi, and Yangzhou. Nanjing demonstrates a pattern of slow growth, Wuxi exhibits initial growth followed by a decline, and Yangzhou experiences rapid fluctuations in growth. As typical cities in different urban development stages, Nanjing, Wuxi, and Yangzhou exhibit change trends of the integrated urban sprawl force consistent with their urban development stages. The research framework and model of urban sprawl mechanics proposed in this paper offer a novel perspective and methodology for comprehending the current and future levels of urban sprawl. Moreover, this study furnishes valuable insights for relevant authorities in formulating policies to regulate urban sprawl.
基于力学的城市扩张力理论框架:中国南京、无锡和扬州的案例研究
随着城市化进程的推进,城市快速扩张带来的环境挑战已变得无处不在。因此,对城市无序扩张的研究已成为可持续发展工作中的一个重要焦点,强调需要了解城市无序扩张的演变特征和系统机制。然而,现有关于城市无计划扩展机制的研究仍略显零散,缺乏统一的研究框架和理论模型。为此,本文提出了城市无计划扩展机理的理论框架,并构建了统一的分析框架和综合的城市无计划扩展力模型。此外,本文还以南京、无锡和扬州为案例进行了实证分析,通过对城市蔓延综合作用力趋势的比较评估,测度城市蔓延综合作用力并分析其城市蔓延特征。研究结果表明,南京、无锡和扬州三地的城市综合扩张力趋势截然不同。南京呈现出缓慢增长的模式,无锡呈现出先增长后下降的模式,而扬州则经历了快速增长的波动。作为处于不同城市发展阶段的典型城市,南京、无锡和扬州的城市综合扩张力变化趋势与其城市发展阶段相一致。本文提出的城市扩张力学研究框架和模型,为理解城市扩张的现状和未来水平提供了新的视角和方法。此外,本研究还为相关部门制定调控城市无序扩张的政策提供了有价值的启示。
