| 摘 要： | 基于1949—2006年9个时相的数据,运用GIS的多种空间分析方法,对盐城城市内部空间结构、城市形状的演化特征以及城市形态演化的各向异性进行分析。1984—2006年城市空间结构演化过程可划分为集聚、分散、再集聚阶段,1949—2006年城市空间形态演化经历了团块状形成期、星状出现期、星状发展期、圈层出现期;分析盐城城市空间结构演化中存在的问题。

| Abstract: | Based on the data of nine times from 1949 to 2006,taking the advantages of GIS spatial analysis methods such as the growth intensity index,ring system method,equal fan method,Boyce-Clark shape index and so on,this paper made a quantitative study on the dynamic evolution characteristics of urban internal spatial structure and urban shape and the evolution anisotropy of urban form of Yancheng City,Jiangsu Province.It is indicated that the evolution of urban spatial structure of Yancheng City is characterized by obvious stages.1) From 1984 to 2006,the evolution process of urban internal spatial structure can be divided into three stages,i.e.the age of cluster,the age of distribution and the age of again-cluster.2) From 1949 to 2006,the evolution process of urban spatial form can be divided into four stages,i.e.the formation stage of mass shape,the appearance stage of star shape,the development stage of star shape and the appearance stage of ring structure.The evolutionary patterns of urban spatial structure can provide scientific base for the planning and construction of Yancheng City. |
