摘要
随着城市化进程不断深化,城市发展效益研究显得越发迫切,而地理国情成果提供了新的深入分析评价城市发展效益的视阈。本文利用国产高分辨率遥感卫星影像与地理国情普查成果,提取泰州市城区边界及内部结构信息。从时间序列对泰州市城区边界扩张进行动态分析,并结合泰州市2015年内部结构数据分析与江苏省内各城市间的横向比较进行静态分析。在地理信息大数据的基础上结合社会经济信息,从城市空间扩张、城市扩张协调性、城市内部要素、城市人居环境状况等方面对泰州市城市发展效益进行评价。根据泰州市历史发展足迹,结合泰州市各方面较江苏省其他城市所处的发展水平与状态提出结论与建议。这是对地理国情成果价值的进一步挖掘,也是地理信息大数据在社会经济与公共服务领域的深入应用。
With the deepening of urbanization process,the research on the evaluation of urban development benefit becomes more and more urgent. The results of the National Geographical Condition Monitoring provide a new insight into the evaluation of the benefits of urban development. Using high resolution satellite remote sensing images and the data of national geographical condition monitoring,draw the Urban boundary of Taizhou and abstract internal structure information of Taizhou. The paper dynamically analyse urban boundary expansion of Taizhou from time series,and makes a static analysis combined with the analysis of the internal structure data of Taizhou in 2015 and the horizontal comparison between cities in Jiangsu Province. Based on large data of the geographic information and socioeconomic information,the paper evaluates the urban development benefit of Taizhou from the aspects of urban space expansion,urban expansion coordination,urban internal factors and urban human settlements environment. According to the historical development footprint of Taizhou,and combined with the development level and status of Taizhou compared with other cities in Jiangsu Province,this paper puts forward some conclusions and suggestions. This is a further excavation of the results of the National Geographical Condition Monitoring,and also a profound application of the large geographic data in the field of social economy and public service.
