摘　　要：高密度垂直城市的迅猛发展催生了复杂的三维步行网络,使得有效应对复杂条件的精准城市设计分析备受关注。空间设计网络分析工具(sDNA)的发展,为三维步行网络的定量化分析与优化设计带来了可能。以广州第二中央商务区城市设计为例,探索在新技术支持下面向设计的分析方法,以及三维步行网络评估、功能布局调整、垂直交通优化的操作范式。相关分析率先实现了复杂、多基面三维步行网络的设计效能研判与优化,为步行空间的开发、周边功能的组织和垂直交通设计提供科学建议。该研究是数字化城市设计背景下的有益尝试,能有效助力城市设计的精细化、人本化转型,推动科学的设计决策和精准的空间营造。The rapid development of high-density cities contributes to a complex pedestrian network,attracting increasing attention to accurate urban design analysis that can effectively cope with complex conditions.The integration of spatial design network analysis(sDNA)and geographic information system(GIS)is bringing the possibility of quantitative analysis and design optimization to the three-dimensional pedestrian network.This research combines the actual needs of the pedestrian network of Yuzhu and Yufengwei Station to explore design-oriented analysis methods.It attempts to explore an operation paradigm of 3D pedestrian network evaluation,functional layout adjustment and vertical transportation optimization with the support of sDNA technique.Results of quantitative data analysis are used to provide scientific advice for the development of pedestrian network,organization of peripheral functions and vertical connector design.This research is an attempt of digital urban design,which can effectively contribute to the fine-scale humanoriented urban design,promoting more scientific regeneration decisions and more precise space creation.
