| 基于多期明光市历史地图与1980-2020年五期Landsat遥感影像图,复原了明光市6个时间截面下城市建成区范围与城市道路网络,综合运用分形理论与空间句法理论,分析了明光市城市外部空间形态和内部空间结构的时空演变特征。结果表明：①明光市城市空间扩展经历了四个阶段：起步阶段(1949-1980)、探索阶段(1980-2000)、成长阶段(2000-2010)、加速阶段(2010-2020),城市整体呈扇面状向东北扩展,外部空间形态由简单趋向于复杂,由紧凑趋向于松散；②全局集成核范围不断扩大,集成核向东北方向转移。③局部空间与整体耦合度较好,新旧城区联系度有待加强；④明光市城市内外空间协同演变,城市空间扩展方向与集成核转移方向一致,内外空间发展相互引促进。 |

| Based on the multi-phase historical map and the remote sensing image date from 1980 to 2020,this paper restored the urban spatial form and road network of Mingguang City in s1949,1980,1990,2000,2010 and 2020,by using fractal theory and space syntax, analyzes the evolution characteristics of urban exterior spatial form and interior spatial structure. Results display: ①From 1949-2020, the expansion of urban external land has experienced four development stages : the initial stage (1949-1980), exploration stage (1980-2000), growth stage (2000-2010), acceleration stage (2010-2020).The city expands to the northeast in the shape of a fan, and the external space form tends to be complex from simple, and from compact to loose; ②The global integrated core is continuously expanding, shifting to the east and north gradually;③ There is high couplingbetween the local space and the whole space, but the connection between the old and new urban areas needs to be strengthened;④There is a significant spatio-temporal linkage between the nterior space and exterior space.The expansion direction of urban space is consistent with the direction of integrated core transfer, and the development of internal and external spaces promotes each other. |
