摘要：

本文结合地理信息系统与空间设计网络分析软件, 以香港中环地区的多层面步行体系为例，分析三维建成环境的空间网络，测度高密度多层面建成环境空间和人的活动分布之间的关系。对室外步行网络模型与室内+ 室外步行网络模型的比较表明，完整的室内外三维模型不仅有助于提升空间网络分析的可视化，其分析得到的穿行度指标与城市空间活力之间的关系也更加精确，有助于城市设计师解码人本尺度的空间认知与行为。

Abstract：

This paper proposes a new GIS based spatial design network analysis (sDNA+) that can be used in three-dimensional built environment. Spatial configuration and its relation to pedestrian movement are quantitatively analysed in the case of Hong Kong Central area. The comparison between outdoor only and indoor + outdoor 3D pedestrian networks shows that it is unrealistic to study the multilevel pedestrian network in high density built environments by only considering the outdoor pedestrian network. Indoor + outdoor 3D pedestrian network helps designers and researchers to decode human-centred spatial configuration and pedestrian activity patterns.
