摘　　要：以池州市贵池区2004—2018年的城市空间形态变化为研究对象,使用基于ArcGIS平台的空间句法分析工具和空间自相关性分析工具对其道路结构进行分析,探究以贵池区为代表的沿江小城市空间结构分布特征和影响因素。研究表明:“飞地”式发展可有效突破自然瓶颈,快速拉开城市空间框架,但“飞地”的选址需紧密依托外部优势条件。城市空间扩展过程中道路的可达性指标并非简单的线性升高,新旧城区道路的相关指标的变化过程存在着显著差异。城市对外服务职能是促进城市空间形态优化、发展水平上升的根本动力。只有积极提升对外服务职能,才能促进沿江小城市的空间扩展良性有序进行。Taking the change of urban spatial form in Guichi District of Chizhou City from 2004 to 2018 as the research object,the ArcGIS-based spatial syntax analysis tool and spatial autocorrelation analysis tool were used to analyze its road structure,and the distribution characteristics and influencing factors of the spatial structure of small cities along the Yangtze River represented by Guichi District were explored.The research shows that“enclave”development can effectively break through the natural bottleneck and quickly open the urban spatial framework.However,the location of the“enclave”should be closely dependent on external advantages.In the process of urban spatial expansion,the indicators of road accessibility do not simply increase linearly,and there are significant differences in the change process of the relevant indicators of roads in new and old urban areas.Urban external service function is the fundamental driving force to promote urban spatial form optimization and development level rise.Only by actively enhancing the external service function can the spatial expansion of small cities along the Yangtze River be carried out in a benign and orderly way.
