摘要:

在新时期城市更新的战略背景下，基础设施改造升级面临着技术封闭、空间割裂和社会区隔等多重矛盾。以社会学“场域理论”为理论支点，融汇“基 础设施都市主义”的跨学科视角，提出“场域基础设施”理论，为城市基础设施复合化转型提供系统性指导。以“同构-互构-重构”3层递进逻辑构建理论框架： 1)“空间-社会”的拓扑关系同构；2)“物质-社会-象征”的三元空间互构；3)“场域基础设施”的多域维度重构。理论框架由相互作用和映射的“物质-社会象征”场域，以及“7+X”多域维度构成。后者作为动态变量，包括安全、政策、经济、生态、文化、技术和社会7个基本维度与作为变量的X维度。通过探索理 论结合实际需求的“多域”关系重构及其作用机制，倡导以“场域基础设施”为导向的建成环境再生的范式创新。

Abstract:

Within the strategic agenda of contemporary urban regeneration, infrastructure retrofitting and upgrading must confront intertwined challenges of technological enclosure, spatial fragmentation, and social segregation. Grounded in Bourdieu’s field theory and enriched by the interdisciplinary lens of infrastructural urbanism, this study advances a "Field Infrastructure" theory to systematically guide the composite transformation of urban infrastructure. The proposed framework unfolds through a three-stage logic - isomorphism, interconstruction, and reconstruction - 1) revealing the spatial-social topological isomorphism, 2) explicating the dynamic interconstruction among material, social, and symbolic spaces, and 3) reconstructing the "7+X" multifield dimensions of field infrastructure. It consists of mutually mapped material, social, and symbolic fields, together with a dynamic "7+X" schema that integrates seven fundamental dimensions - security, policy, economy, ecology, culture, technology, and society - with an open X dimension reserved for emerging variables. By exploring the mechanisms through which these multifield relationships can be reconfigured to meet practical needs, the framework advocates a field-infrastructure-oriented paradigm for regenerating the built environment and advancing integrated urban-infrastructure transformation. Toward an integrated transformation of urban infrastructure, paradigm innovation can be summarized in five key shifts. First, a change in cognitive perspective: this study regards infrastructure as a phased outcome of the contest among capitals and actors within specific fields. Second, an expansion of analytical dimensions: by moving beyond singlefactor metrics and introducing a "7+X" multi-domain framework, resources can be flexibly allocated to meet diverse development demands in different field scenarios. Third, an upgrade of the driving logic: the "topology-game" model explains how various capitals and actors interact within infrastructure, elevating static construction to dynamic governance. Fourth, the fusion of design domains: cross-disciplinary strategies address urban development issues, with landscape architects - through cross-scale integration - playing a pivotal coordinating role. Fifth, an enhanced value orientation: guided by the principles of the "People-Centered City" and "Beautiful China", the framework advocates public interest and ecological priority. "Field Infrastructure" serves both as a theoretical framework and practical paradigm for analyzing and reconstructing the dynamic relationship between urban space and the social environment, and as a tangible object in landscape design practice. Theoretically, it enables analysis of how capitals and power relations - under dynamic variables - jointly shape the material urban space, providing a dynamic strategic framework for compound infrastructure transformation. Practically, "Field Infrastructure" is a composite spatial carrier that organically integrates physical urban infrastructure with landscape public space. By interweaving infrastructure and public space, it transcends the single-function technical rationality, offering a comprehensive planning paradigm and action program for contemporary cities.
