| 摘 要： | 城市空间格局变化监测能够反映城市建设空间的发展规律和特点,为城镇体系发展规划、优化以及城市空间开发集约利用等提供重要基础。该文选取山东省作为研究区域,以全省17个地级以上城市城区为研究对象和统计分析单元,以2000-2017年7个时期高分辨率正射影像提取其城区边界和部分时期内部结构数据,采用城市扩展面积、城市扩展速度、城市扩展强度及紧凑度等指标,对山东省17个地级市城市空间格局发展变化进行综合分析,对城市扩展、城市用地等进行评价。研究结果表明:山东省地级以上城市空间格局演变整体呈现出以济南青岛为中心的东西两极发展格局,整体发展较为均衡,但东西部差距依然较大。城市紧凑度较低,以粗放型土地增长模式扩展,面积扩张过快,占用耕地比例较高,土地集约利用程度不够。研究成果可为优化城市空间结构,促进城镇高效、集约、节约、绿色发展等提供了合理的建议以及技术支撑。

| Abstract: | The monitoring of urban spatial pattern change can reflect the space development law and characteristics of urban construction. It can provide an important foundation for urban system development plan and intensive use of urban space development. Selecting Shandong province as the research area, regarding districts in 17 prefecturelevel cities as the research object and statistical analysis unit, urban boundary data and internal structure data for some periods of 17 cities have been extracted based on highresolution orthophotos from 2000 to 2017. By using urban expansion area, urban expansion speed, urban expansion intensity and compaction, the development and changes of urban spatial pattern in 17 prefecturelevel cities in Shandong province have been analyzed comprehensively, and the urban expansion and urban land use have been evaluated. It is showed that the evolution of urban spatial pattern in Shandong province develops in a balanced mode. Ji''nan and Qingdao are two development centers in Shandong province. There is a big gap between the cities. Most cities have a lower level of compactione and an extensive extension models. Urban area expansion is too fast and occupied excessive cultivated land. The research result can provide reasonable suggestions and technical support for urban spatial pattern optimization and conducives to the development of the cities. |
