常州市城市空间格局监测分析

Monitoring analysis of urban spatial pattern in Changzhou city

城市空间格局是反映城市空间扩展的最直观标识,文章以地理国情监测成果、遥感影像数据为基础,提取常州市2015年、2016年、2017年三期城市建成区边界,构建了常州市城市空间格局监测分析指标,分析监测常州市城市格局的变化特征和空间扩展的差异,并进一步分析了常州市扩展的区域差异。结果显示:常州市主城区发展进入相对稳定的阶段,溧阳市发展较快;空间扩展方面,2015-2016年增速相对较快,而2016-2017年相对平稳。

The urban spatial pattern is the most intuitive indicator reflecting the expansion of urban space.Based on the results of the national conditions monitoring and the remote sensing image data,this study extracts the boundary of urban built-up areas in Changzhou city in 2015,2016 and 2017.The monitoring and analysis indicators of urban spatial pattern of Changzhou city are constructed,and the variation characteristics and spatial expansion of urban pattern in Changzhou are analyzed.And it further analyzes the regional differences in Changzhou’s expansion.The results show that the development of the main city of Changzhou has entered a relatively stable stage,and the development of Liyang city is relatively fast.In terms of space expansion,the growth rate in 2015-2016 is relatively fast,while the 2016-2017 is relatively stable.
