徐州运河城镇空间格局演变及其形成机理

Evolution and formation mechanism of Xuzhou canal town spatial pattern

运河城镇作为运河繁荣的见证,是大运河文化带建设的主体.以徐州运河城镇为研究对象,运用文献分析、田野调查、地图图谱分析等研究方法,探究徐州运河城镇空间格局演变过程、演化特征和形成机理.研究发现:徐州运河城镇空间格局演变过程历经5大阶段,具有阶段递进性;演化特征呈现运河烙印性,具有沿运分布的空间根植性、通盛废衰的格局转换性、内部结构的职能协同性、城镇体系的等级位序性等特征;演化影响因素具有多元复合性,深受自然水系、南经北政格局、黄河变迁、铁路贯通、新近国家与区域发展战略等因素影响.

As the witness of canal prosperity,canal towns are the subject of the Grand Canal cultural belt construction.Taking Xuzhou canal towns as the research object,using the methods of literature analysis,field investigation and map analysis,the process,characteristics and mechanism of the spatial pattern of Xuzhou canal towns are analyzed.The main conclusions are as follows:the spatial pattern evolution of the Xuzhou canal towns is divided into five progressive stages.The formation and evolution of spatial pattern are closely related to the Canal,which has the characteristics of spatial embeddedness along the Canal,spatial pattern transformation due to prosperity or decline of canal channel,functional coordination of internal structure,and hierarchical order of urban system.Factors of the spatial pattern evolution are multiple and complex,which are deeply influenced by natural water system,North-South economic and political pattern,Yellow River change,railway connection,and recent national and regional development strategies.
