规划遗产为规划史和遗产保护研究提供了新的视角，对清晰揭示城市遗产的完整性内涵具有重要意义。然而，当前规划遗产相关学术研究主要聚焦于理论层面的探讨，缺乏对实际案例尤其是社会主义城市规划中“政治性空间”的研究，该类规划遗产历史演变过程中多重范型叠加与调适机制未被充分揭示。因此，文章以兰州市东方红广场为例，采用大数据文本挖掘与空间形态参数化提取的研究方法，从兰州历版城市总体规划（1954—2035年）的纵向时序中，解构政治集会型广场的历史并进行范型演变总结。结果表明，东方红广场作为规划遗产，其历史范型演变遵循“政策—技术—社会”协同演进的作用路径。在政策层面，从“国家意志主导”转向“多元主体共治”，治理工具从行政指令转变为技术与制度的协同治理；在技术层面，从单一意识形态象征拓展为“生态-经济-文化”的复合体，更新过程中呈现明显层积效应；在社会层面，本土化创新贯穿始终，无论是苏联模式主导的适应性改造，还是传统模式与当代生活圈的融合，均彰显其规划智慧。

Heritage planning offers a new approach to researching planning history and heritage conservation,playing a vital role in clarifying the concept of urban heritage integrity.However,current academic studies on planning heritage predominantly focus on theoretical discussions,paying insufficient attention to practical case studies,particularly those concerning the"political spaces"within socialist urban planning.The overlapping paradigms and adjustment mechanisms underlying the historical evolution of such planning heritage remain inadequately explored.Taking Dongfanghong Square in Lanzhou City as a case study,this paper employs big data text mining and spatial form parameterisation extraction.By deconstructing the history of political assembly squares within Lanzhou's successive master plans (1954–2035),it summarises paradigm shifts.The findings indicate that Dongfanghong Square,as planning heritage,has evolved along a"policy-technology-society"pathway.At the policy level,there has been a shift from"state-led governance"to"multi-stakeholder co-governance",with governance tools transitioning from administrative directives to technologyinstitutional synergistic management.Technologically,the square has expanded from a singular ideological symbol to a composite entity encompassing ecological,economic and cultural dimensions,exhibiting pronounced stratification effects during renewal processes.Socially,localised innovation has remained a constant theme,whether in the form of adaptive modifications under Soviet-inspired models or the integration of traditional patterns into contemporary living environments.Both of these aspects highlight the planning wisdom of the area.
