当代城市设计实践中的“形态结构”探讨

Exploring the“Morphological Structure”in Contemporary Urban Design Practices

梳理了城市形态及其结构的概念、层级和内涵,分析了中微观尺度下城市形态的组成要素,明确了结构性要素对于城市塑形和意象认知的关键作用。基于4个城市形态发展期和大量当代城市设计案例的特征抽取,提出由自然特质、城市轴、地标物、公共开敞空间、建筑形态、活动基面6类结构性要素组合形成的"城市形态结构",并结合当代城市设计实践阐述形态结构塑造中的关键点。

E xplicating the concept s,layer s and connot ations of urban morphology and its structure,this paper analyzes the components of urban form on medium and micro scale,and clarifies the central role played out by structural elements in urban formation and imager y perception.Based on a characteristic analysis of four typical periods of urban morphological development and ample examples of contemporary cases,it identifies six structural elements comprising urban morphological structure-natural properties,urban axis,city landmarks,public open space,architectural form and urban interface.In conclusion,the paper explicates the key points in shaping morphological structure based on case studies of contemporary urban design practices.
