【摘要】：将城市不透水地表盖度产品应用于城市群空间结构研究具有重要价值。本文基于多源遥感数据提取了"京津冀"与"波士华"城市群近40年(1972-2011年)亚像元级不透水地表专题信息,构建了城市群空间结构对比分析数据集;并引入引力模型和景观格局理论,利用引力指数、景观格局指数以及空间结构参数等,采用地理信息系统空间分析方法,从城市群与城市两个尺度对城市群空间结构进行了对比研究。结果表明:(1)"京津冀"城市群不透水地表快速增长,而"波士华"城市群较为稳定;(2)"京津冀"城市群空间结构经历了城市孤立发展阶段、双核心城市群阶段、城市群组阶段以及城市群网络化阶段,"波士华"城市群空间结构较为稳定,空间结构呈现出"点—轴"带状分布;(3)中国城市不透水地表盖度"高—高"聚集区呈现出典型团块状"摊大饼"形态,而美国城市呈现出一种"多中心集聚、分散成组"的态势;(4)"京津冀"城市群生态、生产与生活用地不透水地表面积占比均高于"波士华"城市群。最后,基于两国城市群空间结构的对比结果,从空间布局优化角度对"京津冀"城市群的发展提出了初步建议。
[Abstract]:It is of great value to study the spatial structure of urban agglomeration by using urban impermeable surface coverage products. In this paper, "Beijing-Tianjin-Hebei" and "Boshihua" urban agglomerations have been extracted from multi-source remote sensing data for nearly 40 years (. 1972-2011) subpixel level watertight surface thematic information. The data set of spatial structure contrast analysis of urban agglomeration is constructed. By introducing the gravitational model and landscape pattern theory, using the gravity index, landscape pattern index and spatial structure parameters, the spatial analysis method of GIS is adopted. The spatial structure of urban agglomeration is compared with that of urban agglomeration. The results show that "Beijing-Tianjin-Hebei" urban agglomeration has a rapid increase in impermeable surface, while "Bosch Hua" urban agglomeration is more stable. 2) the spatial structure of "Beijing-Tianjin-Hebei" urban agglomeration has experienced the stage of urban isolated development, the stage of dual core urban agglomeration, the stage of urban group and the stage of urban agglomeration networking, and the spatial structure of "Boshihua" urban agglomeration is relatively stable. The spatial structure shows a "point-axis" zonal distribution. (3) the "high-high" accumulation area of impermeable land surface in China presents a typical "spread cake" shape, while the American city presents a situation of "multi-center agglomeration, dispersed into groups"; (4) the proportion of impermeable land surface area of "Beijing-Tianjin-Hebei" urban agglomeration is higher than that of "Boshihua" urban agglomeration. Finally, based on the comparison of spatial structure of urban agglomeration between the two countries. From the angle of spatial layout optimization, the paper puts forward some preliminary suggestions on the development of Beijing, Tianjin and Hebei urban agglomeration.
