摘　　要：空间基因承载着“城市空间-自然环境-社会人文”互动演化模式的空间信息,在城市空间文脉传承中起着关键性作用。一直以来,以建成环境遗产保护、符号复制或形态模仿方式进行的城市文脉传承,忽视了对空间基因的关注,导致即使存“物”,也失“脉”。因此,在城市研究中运用空间基因理论,深入理解空间基因的内涵与作用机制十分必要。城市空间形态(性状)的发展规律可以运用“空间基因”解释:通过“变异”与“选择”,生成空间基因这一地域性空间组合模式,从而决定城市空间的某些性状;然后,通过“编码”“复制”与“表达”,实现城市空间文脉的传承。“空间基因”研究可以使城市历史文脉保护与规划设计方法产生方向性转变,使其从感性的空间形式模仿或创作,走向理性的空间建构规则分析,是修正当前对城市空间发展错误认知、改进规划设计策略与方法的重要基础。Space gene,which carries spatial information of the interactive evolution pattern of urban space,natural environment,and social culture,plays a significant role in the inheritance of urban spatial context.However,the inheritance of urban spatial context has been always carried out by protecting heritage sites,copying symbols,or imitating the form of the built environment,yet little attention was paid to space gene,resulting in the loss of city spirit even if the heritage site is preserved.Therefore,it is necessary to understand the connotation and functional mechanism of space genes and to apply the space gene theory into urban studies.First,the development laws of urban form(character)could be explained by space gene.Space gene is generated as a local spatial model through mutation and selection,then the urban spatial context is inherited through its coding,copying,and expressing,to achieve the inheritance of urban spatial context.Second,the research of space gene could change the direction of urban historical context protection and planning and design method from perceptual space form creation to rational space gene analysis.It is an important basis for correcting the wrong cognition of urban spatial development and improving planning and design strategies and methods.
