摘要
滁州市建成区扩展变化的研究,有助于了解滁州市的城市时空变化,对滁州市的城市规划具有重要意义。本研究基于遥感和GIS技术,利用滁州市2013、2015、2018年3期TM遥感影像,采用NDBI、监督分类(最大似然法)和非监督分类三种方法对滁州市的建成区进行提取比较。并利用扩展强度指数和紧凑度指数等方法,借助GIS的空间分析功能,对滁州市城市建成区扩展变化进行分析,结合滁州市经济统计报告数据,从人口、经济、交通等方面对滁州市建成区扩展变化及驱动力进行了分析。研究表明:建成区面积的增长与GDP和人口都呈十分显著的正相关关系,且与交通便捷度也存在一定的联系。
The study on the expansionary change of the built-up area of Chuzhou City helps to understand the change in urban space and time of the city, which is of great significance to the city planning. Based on remote sensing and GIS technology, using TM remote sensing images of the city in 2013, 2015 and 2018, this study extracts and compares the built-up area of the city by NDBI, supervised classification(maximum likelihood method) and unsupervised classification, and analyzes the expansionary change of the built-up area using expansion intensity index, compactness index, and spatial analysis function of GIS, and probes into the change and driving force of the city in view of population, economy and traffic using the data of economic statistics report. The study shows that the increase in the built-up area is positively correlated with GDP and population, and is also correlated with traffic convenience.
