空间句法与sDNA在传统村落空间网络中的对比研究

Comparative study of spatial syntax and sDNA in traditional village spatial network

摘要

空间设计网络分析(spatial design network analysis，sDNA)的应用研究可为传统村落的保护规划工作提供技术理论支持。文章基于空间句法与sDNA的理论及功能分析，阐明sDNA在传统村落保护规划中的可行性，通过传统村落中的应用实践分析明确两者的使用范畴。结果表明:空间句法与sDNA的基础理论背景和空间网络的外在属性相同；sDNA构建路网的编码方式可以展现道路真实形态，其计算结果的准确性较高；sDNA适合应用于传统村落的街网分析，同时能够提供更加全面细致的分析结果；传统村落中sDNA的三维分析结果与其二维分析结果无明显差异；sDNA的灵活度较高，可通过调整参数、赋予权重等方法获得需要的分析结果，空间句法则更适合大尺度的空间结构以及空间网络的全局分析。

Abstract

Application-oriented research on spatial design network analysis (sDNA) provides technical and theoretical support for the conservation planning of traditional villages. Based on the theoretical frameworks and analytical functions of space syntax and sDNA, this study examines the feasibility of applying sDNA to traditional village conservation planning and clarifies the respective scopes of the two methods through practical case analysis. The results indicate that the two approaches share similarities only in their fundamental theoretical background and the external attributes of spatial networks. The road network encoding method in sDNA can accurately represent the actual morphology of streets, leading to higher computational accuracy. sDNA is particularly suitable for analyzing street networks in traditional villages and can generate more comprehensive and fine-grained analytical results. No significant differences are observed between the 3D and 2D analysis results of sDNA in traditional village contexts. Moreover, sDNA demonstrates high flexibility, allowing tailored analytical outcomes through parameter adjustment and weighting schemes, whereas space syntax is more appropriate for large-scale spatial structure and global network analysis.
