摘要: 针对现代城市空间活力缺失问题，相关研究已经初步证实复杂网络与空间活力的关联性，但是这一关系的具体空间表 征机制尚不明确。通过复杂网络结构属性与活力形态的作用关系探讨，发现城市空间活力的3项构成规律：节点集聚与 混合引致高密度多样化功能、路径连接与可达构成关联性街道体系、尺度分形与交互塑造宜人空间环境。应用“空间— 活力”相关性测度模型，以重庆市中心城区12个空间单元为研究对象进行形态推演，分析活力值与复杂网络耦合关系， 证实了空间活力生成机制的合理性。根据分析结果，提出城市活力空间设计导控路径，包括空间多元属性认识、路径非 线性层级构成、空间场所互动关联设计3个方面，并展开行为活力机制、时间演变规律等角度的后续研究探讨，以期对 当下我国城市多维信息叠加的活力营建有所借鉴。
Abstract: Facing the shortage of spatial vitality in modern cities, relevant studies have confirmed the relationship between complex networks and spatial vitality, but the specific presenting mechanism of this relationship is still not clear. According to the discussion on the relevance between complex network's structure and vitality form, this paper discovers three principles of urban spatial vitality, including gathered and mixed nodes causing functions' intensive diversification, connecting networks constituting accessible street systems, and fractal and interactive scale shaping pleasant space. Based on these principles, it builds up a correlation test model of space and vitality, takes 12 downtown spatial units of Chongqing as the research objects, and applies the morphological deduction method to analyze the coupling relationship between vitality value and complex network, confirming the rationality of the spatial vitality's generating mechanism. According to the conclusions in the test, the paper puts forward the regulatory paths of urban vitality space design, including attribute understanding of spatial diversity, the nonlinear and layered paths' constitution, and the interacting design of spaces. Meanwhile, the paper carries out the follow-up research from the perspectives of behavioral vitality mechanism and vitality evolution disciplines, to inspire the current construction of dynamic urban space in a multi-dimensional information environment.
