摘　　要：通过建立K均值聚类法与形态类型学结合的分析框架,对大尺度山地旧城区的地块肌理形态进行量化识别。以重庆渝中旧城区为例,利用分析框架识别出超级地块、大地块和开放地块等6种地块类型,细分肌理、粗放肌理和开放肌理等5类地块肌理,分析不同肌理类型对应的建成空间形态的差异,认为不同肌理类型的形成和发展受到土地开发制度、城市发展政策与建设管控模式等因素的综合影响,在传统形态时期、计划经济时期和快速更新时期3个形态演变阶段呈现出不同的特征,并塑造了东西分异的旧城整体地块格局。在此基础上,从空间形态、历史保护、规划管控3个层面提出地块肌理形态管控建议,以促进旧城的有机更新。An analytical framework combining K-means clustering method and typo-morphology theory is established to realize the quantitative identification of plot patterns in the old urban area of large-scale mountainous city.In the empirical study of Yuzhong district in Chongqing,6 types of plots and 5 types of plot patterns are identified,including fine divided pattern,extensive pattern,open pattern,steep slope pattern and mixed pattern.Different pattern types correspond to significantly different built spatial forms;their formation and development are affected by land development systems,urban development policies,and construction control models,and can be divided into three evolution stages:the traditional form period,the planned economy period,and the rapid renewal period.The development of plot pattern types also shaped the overall plot pattern of the old urban area,which is differentiated from east to west.Finally,from the three aspects of urban form,historical protection,and urban planning management,suggestions are put forward for the management and control of the plot pattern so that the regeneration of the old city can be promoted.
