Parametric Technology-Driven Restructuring of Roadway Spatial Texture in Xinghua Jindongmen Historic District: An Urban Morphology Study

针对兴化金东门历史街区道路空间肌理重构问题，通过参数化技术框架建立量化分析方法。运用CityEngine三维建模技术解析街区空间特征，开发参数化生成算法形成多维度重构方案。实证研究表明，该方法有效提升了道路通达性与公共空间可达性，同时保持了历史街区风貌完整性，较好地平衡了文脉传承与现代功能需求，推动街巷空间环境的可持续性发展。具体而言，参数化算法通过减少道路冗余建设，显著降低了更新过程中的隐含碳排放，契合环境经济学中全生命周期评估的低碳城市更新架。所形成的参数化设计流程为历史街区保护更新提供了数字化技术工具，其技术路径对城市规划、建筑的可持续更新设计与遗产保护领域具有实践参考价值。This study develops a parametric framework to quantitatively analyze and reconstruct the roadway spatial texture of Xinghua Jindongmen Historic District. Utilizing CityEngine 3D modeling to decode spatial features and parametric algorithms to generate multi-dimensional schemes, the method demonstrably enhances road accessibility and public space permeability while preserving historical authenticity. It effectively balances heritage conservation with modern functional needs, promoting sustainable alleyway development. Specifically, the approach reduces embodied carbon emissions by minimizing redundant construction, aligning with low-carbon urban regeneration principles under life cycle assessment. The resulting parametric workflow provides a digital tool for historic district renewal, offering practical value for sustainable urban planning, architectural renovation, and heritage conservation.
