摘要:
对城市空间扩展进行动态监测,有助于把握城市空间格局的结构性特征和发展模式,其监测数据可以为构建科学合理的城市化格局、生态安全格局和实现紧凑集约、高效绿色发展提供基础依据。文章基于多光谱遥感影像数据和专题资料,利用空间象限方位、紧凑度、分形维数等计算方法,对2000至2017年济南市城区空间扩展进行了研究。结果表明:2000至2017年间,济南市主要沿东西方向扩展,平均扩展速度为13.07 km2/a;在5个监测时段,济南市城区的分形维数值均>1.5,城区边界图形复杂,紧凑度指数均< 1,形状紧凑度较差,扩展类型由外部扩展向内部填充转变;济南市新增城区的土地来源主要为耕地,其次为建设用地,且逐年的耕地占比减少,建设用地占比增高。
Abstract:
Dynamic monitoring of urban spatial expansion is helpful to grasp the structural characteristics and development model of urban spatial pattern. It will provide base data not only for building scientific and reasonable urbanization pattern and ecological security pattern, but also for achieving compact intensive and efficient green developing. By using multispectral remote sensing image data of the Jinan City from 2000 to 2017, the urban boundaries is exacted based on the definition and the differentiation principle. The extension area, extension speed, extension orientation, extension form and land use type of the urban area are analyzed by using calculation method like spatial quadrant azimuth, compactness, fractal dimension, etc. The results show that Jinan City develops rapidly in the past 17 years, mainly extending in the EastWest direction, with an average expansion speed of 13.07 km2/a. The fractal dimension values of the five monitoring phases are all greater than 1.5 which means the urban boundary graphics is complex. The compactness index is much less than 1. The shape compaction is poor, and the expansion type changes from external expansion to internal filling. From 2000 to 2017, the land source of the newly added urban areas is mainly arable land, followed by construction land. The proportion of arable land decreases year by year, and the proportion of construction land increases.
