摘　　要：基于景观都市主义中人工地形概念,尝试提出一种研究多层步行系统地形特征的模型,并在城市设计情景中对其进行评测。高程转换与正"外部性"所驱动的潜在活动节点连接是决定这一空间特质的重要参数。本研究的结果可以解释现存的城市设计准则,并为实测的事实数据与学科性知识之间搭建桥梁。On the basis of the concept of artificial topography in landscape urbanism, this paper proposes a research model to study the topographical characteristics of a pedestrian net work and testify to its applicability in the urban design scenarios. Grade changes and the connections of activity nodes driven by positive ＂externalities＂ are the two key variables which determines the spatial quality of a multi-level pedestrian network. The research contributes to interpreting the existing urban design norms and connecting measurable facts with disciplinary knowledge.
