| 中文摘要: |
| 基于历史地图与 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起步、探索、成长、加速四个阶段，城市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）城市全局集成核范围不断扩大，集成核向东北方向转移，局部与整体耦合度较好，但新旧城区联系度有待加强；3）城市内外空间协同演变，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；4）从明晰发展方向、空间集约发展、优化交通网络三个角度为明光市城市空间发展提出引导建议。 |
| 英文摘要: |
| Based on the historical map and the remote sensing image data， the urban spatial form and road network of Mingguang City in 1949，1980，1990，2000，2010 and 2020 are restored to analyze the evolution characteristics of exterior spatial form as well as interior spatial structure with the fractal theory and space syntax. The results show that：1） The evolution includes four stages：startup，exploration，growth and acceleration. The city expands in a fan-like pattern to the northeast，and the space form tends to be more complex and looser；2）The integration core is continuously expanding from the east to the north，and the coupling between the local space and the whole space is good，while the connection between the old and new urban areas needs to be enhanced；3）The interior and exterior spaces co-evolved，as the expansion direction of urban space is consistent with the expansion direction of the integration core；4）Suggestions for Mingguang City development are put forward from three perspectives：development direction selection，space intensive development and traffic network optimization. |
