【摘要】 山地历史城镇作为我国独特的聚落空间载体，具有重要的保护价值。传统空间结构的延续是古镇形态保护的基础，但定量标准的缺失使古镇空间结构保护具有较大的不确定性。选取重庆市丰盛古镇为研究对象，采用轴线—视域的拓扑方法对古镇保护规划实施前后的空间结构进行对比研究，提取古镇空间特征并对其格局变化的形成原因加以分析，进而提出针对性的保护对策与建议，为古镇格局保护的量化评价及策略制定提供思路。更多还原

【Abstract】 As a unique settlement space carrier in China,mountainous historical towns have important protection value.The continuation of traditional spatial structure is the basis of ancient town form protection,but the lack of quantitative standards makes the protection of ancient town spatial structure more uncertain.This paper selects Fengsheng ancient town in Chongqing as the research object,uses the axis view topology method to compare the spatial structure before and after the implementation of the ancient town protection plan,extracts the spatial characteristics of the ancient town,analyzes the causes of its pattern change,and then puts forward targeted protection countermeasures and suggestions,so as to provide ideas for the quantitative evaluation and strategy formulation of the ancient town pattern protection.更多还原
