网络演进引导城市空间特色的自然营建——以安徽省三市为例

Network Evolution Guides the Natural Construction of Urban Spatial Characteristics:Taking Three Cities in Anhui Province as Examples

新马克思主义城市学者认为,快速城市化进程中城市空间发展的本质是一种以建成环境为投资对象的“空间生产”。在这一过程中,自然空间被视为最理想的空间生产对象,在资本的运作下持续遭遇侵占和割裂,日渐淡化了服务大众的公共属性。文章提出将生态网络作为一种捍卫城市空间特色的“空间工具”,超越当前“空间生产”的局限性,站立更广阔的时空维度进行理性思索与科学建构,引导一种内涵式的特色空间“生产”方式。结合安徽省域范围内的山地型、丘陵型和平原型三种类型城市(宁国市、淮北市、淮北市),基于历史层积回溯城市变迁脉络,探寻城市长久以来的“自然记忆”与生态适应性,进而通过积极的网络演进策略与自然建构手段,在生态自组织与空间他组织的交互演替中构建由多元生态空间共同构成的网络化生态空间体系,并阐述了利用该体系积极干预城市空间形态,引导塑造特定类型城市空间特色的基本逻辑。研究探索了一种从非建设用地着手,建构建设用地的良好结构与形态的空间增长方式,以促进城市整体形态与生态环境大格局的优化。

Neo-Marxist urban scholars argue that in the process of rapid urbanization,the essence of urban spatial development lies in"spatial production',where the built environment serves as an investment object Within this context,natural space is considered the most optimal object for spatial production.However,under capitalist operations,it becomes fragmented and encroached upon,gradually losing its public attribute of serving the public.To address this issue,this article proposes employing a networked urban ecological space system asa"spatial tootosafeguardthe characteristicsofurbanspace.By transcending historical limitations and adopting a larger spatiotemporal dimension for rational thinking and scientific construction methods,we aim to explore cities'long-term"natural memory"and ecological adaptability based on tracing their historical changes.Through an active strategy of network evolution and natural construction methods,our approach relies on the interactive succession between ecological self-organization and spatial self-organization to construct a networked ecological space system composed of multiple ecological spatial elements.This system actively intervenes in shaping the form and structure of urban spaces by adapting to diferent types of cities within Anhui Province such as mountainous cities(e.g.,Ningguo),hilly cities(e.g.,Huainan),plain cities(e.g.,Huaibei),etc.Furthermore,this article investigates a spatial growth method that involves transforming non-construction land into well-structured construction land.This approach guides the optimization of overall urban form and patterns within an ecological environment.
