基于夜间灯光数据的淮海城市群空间扩张及驱动力研究
|
摘要
基于2001,2005,2009,2013年的DMSP/OLS夜间遥感影像数据,以淮海城市群为研究对象,综合运用指标指数比较分析法、GIS空间分析法和回归分析法,研究其空间扩张及形态演变特征,并揭示其空间扩张动力.结果表明,研究期内淮海城市群城市空间扩张明显,呈现东北—西南—西北的空间增长特征,形态上表现为以"同心圆"式向外扩张,且沿主要交通干线蔓延.建成区重心基本位于徐州,徐州是区域发展的核心.整体空间形态较为简单,空间填充能力强.市场力是城市群扩张的主要动力,其次为行政力与内源力,外向力影响最弱.趋势上,行政力影响下降,而外向力和内源力影响增强.
Based on the DMSP/OLS nighttime remote sensing image data of 2001,2005,2009 and 2013,the Huaihai urban agglomeration was used as the research object,and the spatial expansion and morphological evolution were studied by using the index comparative analysis method,GIS spatial analysis method and regression analysis method.Features and reveals the power of its spatial expansion.The results show that, during the study period,the urban space expansion of Huaihai urban agglomeration is obvious,showing the spatial growth characteristics of northeast—southwest—northwest,and the form is characterized by "concentric circle" outward expansion and spreading along the main traffic lines.The focus of the built-up area is basically located in Xuzhou City,and Xuzhou is the core of regional development.The overall space shape is relatively simple and the space filling ability is strong.Market power is the main driving force for urban agglomeration expansion,followed by administrative power and internal source power,and the external force has the weakest impact.In terms of trends,the influence of administrative power is declining,while the influence of outward and internal forces is enhanced.
