基于空间句法的旧城中心区空间形态演变研究--以汕头市小公园开埠区为例

摘要

By using space syntax technique,this research aims at taking the morphological evolution of Small Park open port area, Shantou, China from the 1860s onwards. The result shows that two embedded urban renewals played important roles in the evolution. The evolution has mainly experienced three stages, which are self-organization period, urban planning-directed period and commuter network control period. It also illustrates that Small Park area has been featured with the local centrality in different periods;however, with the expansion of city, it has lost its capacity to integrate social and economic activities in the whole city. Finally, three basic elements of the morphological evolution are summarized which include street network, nested structure and geographical position,which can give some methodological suggestions for the renewals of historic centers in Chinese cities.%研究基于空间句法理论与方法，对汕头市旧城中心区——小公园开埠区的空间形态演变进行多尺度分析。结果表明两次嵌入式改造改变了该地区的社会生活本质，先后形成了自发式生长、现代城市规划引导、通勤网络塑造的发展脉络。同时，开埠区在不同时期均保持良好的局部中心性，但与主要城市建成区之间的关系却随着城市扩张而显著减弱。最后，将小公园开埠区的空间形态演变归纳为街巷、嵌套结构与区位三个层次，为其他城市旧城中心区的发展提供借鉴。
