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。  相似文献

东北地区哈大交通经济带经济发展空间差异研究   总被引:2,自引:0,他引:2  
以东北地区哈大交通经济带13个地级市为基本研究单元,以人均地区生产总值为测度经济差异的指标,利用变异系数和泰尔指数对经济带内1987—2006年间的经济发展数据进行总体差异分析,并对差异来源按照行政区划进一步分解,分析影响差异的内、外原因。截取3个具代表性的时间横截面,探究哈大交通经济带空间结构演化特征。结果表明:(1)1987—2006年哈大交通经济带经济地位不断提升,总体差异收缩。(2)1987—1992年经济带差异扩大,主要由黑龙江省内部差异造成;1993—2000年经济带变动微小;2000年以来,哈大交通经济带差异呈现收缩态势。(3)哈大交通经济带空间结构演化特征与地区经济差异时序吻合,未来将呈现带内经济一体化趋势。  相似文献

工业波沿交通经济带扩散模式研究   总被引:17,自引:1,他引:16  
交通经济带是以交通干线或运输通道为发展轴逐步形成的产业和城市高度发达的经济集聚地带。交通经济带是“点轴开发理论”的重要体现形式 ,产业的集聚与扩散是交通经济带形成的基本动力。通过典型经济带的实证分析发现了“工业自生长点沿着交通轴集聚、扩散及再集聚的动态过程”,将其命名为工业波。工业集聚 -扩散的波浪式运动是经济在空间上扩散的一个基本模式。新技术及生产方式首先在最有利的地点逐步成长为增长极。然后沿着交通线逐步向外扩散 ,在有利的地点形成新的生长点。这一扩散过程如同波浪 ,既有波峰 ,也有波谷。增长极与新生长点相互之间在资金、技术、人员、商品营销、原料供应等方面保持着密切的联系。交通轴线是工业波在空间扩散的主要依托基础。轻纺工业、原材料工业等不同工业部门的交通需求有别 ,分别沿着不同的交通线路扩散。  相似文献

长江经济带空间结构演化及重组   总被引:11,自引:1,他引:10  
陈修颖 《地理学报》2007,62(12):1265-1276
在重新认识长江经济带的空间范围及空间结构内涵的基础上,运用空间数据分析的一般方法,获得了长江经济带空间分异的基本特征。经过独立发展阶段、区域集聚与链接阶段、 行政经济区阶段和空间竞争与链接阶段等4 个时期的发展,长江经济带形成了特殊的条形核 心-外围-边缘结构,存在三大核心、一条主轴、一条辅轴、四条地方轴、一个外围地区和 一个边缘地域。运用空间相互作用理论,从互补性、通达性和介入机会等方面分析了长江经 济带空间结构形成与演化的基础。为加快长江经济带空间结构的优化,首先要求空间管理组织的创新,其次是空间结构要素的优化。一个以政府、城市管理与经营者和具有跨国或跨区 域网络的精英企业三者组成的长江经济带空间组织与管理机构,是管理长江经济带的理想组 织模式,只有当政府、城市管理与经营者和企业建立起三者协商与联合的机制,才能进行有 效的空间管理。长江经济带的空间结构要素中,节点和通道是骨架,也是空间结构优化的两 大关键要素。  相似文献

Under the background of China's rapid urbanization, study on comparative analysis of the spatial structure of urban agglomerations between China and the US can provide the policy proposals of space optimization for the Chinese government. Taking the Beijing-Tianjin-Hebei(BTH) and Boswash as study area, we mapped the subpixel-level impervious surface coverage of the BTH and Boswash, respectively, from 1972 to 2011. Further, landscape metrics, gravitational model and spatial analysis were used to analyze the differences of the spatial structures between the BTH and Boswash. The results showed that(1) the area of the impervious surface increased rapidly in the BTH, while those remained stable in the Boswash.(2) The spatial structure of the BTH experienced different periods including isolated cities stage, dual-core cities stage, group cities stage and network-style cities stage, while those of the Boswash was more stable, and its spatial pattern showed a "point-axis" structure.(3) The spatial pattern of high-high assembling regions of the impervious surface exhibited a "standing pancake" feature in the BTH, while those showed a "multi-center, local aggregation and global discrete" feature in the Boswash.(4) All the percentages of the impervious surface of ecological, living, and production land of the BTH were higher than those of the Boswash. At last, from the perspective of space optimization of urban agglomeration, the development proposals for the BTH were proposed.  相似文献

Comparative study of LUCC between Fujian and Taiwan provinces could be a good case for study because of their geographical proximities and historical, cultural similarities. Fujian and Taiwan had gone through and currently are in different economic development stages. Taiwan is in the stage of post-industrialization and Fujian is in the intermediate stage of industrialization. By using the official statistics, changes of built-land in Fujian and Taiwan were analyzed in details. The results showed that these two provinces seemed to have the same characteristics of built-land changes, i.e., accelerating development, and concentrated distribution on both sides of the Taiwan Straits, forming a pattern with the economic layout of two sides acting in cooperation with eath other. If comparing different industrialized areas in Fujian with industrialized stages in Taiwan, it is clear that these two provinces seemed to have the same characteristics of synthesized index of built-land change (Lc), i.e., which is from stabilization or comparative stabilization at the initial stages of industrialization to high ex-pansion at the intermediate stages of industrialization, then followed by low consumption at later stages of industrialization, but the Lc of the initial and the later stages of industrialization in Taiwan were slightly higher than those in Fujian. The results from comparison on relevant indexes have shown: The industrial structure changing rate of Fujian is actually higher than that of built-land in Taiwan, but its using efficiency of regional built-land is also obviously lower than that in Taiwan in the intermediate and later stages of industrialization of Fujian. The major driving forces of the built-land changes in both provinces were analyzed in Causal Models of Path Analysis, and its result indicated that the difference in built-land changes of the two provinces is closely related to their economic development stages and industrial structure. Countermeasure for the realization of sustainable utilization of built-land in Fujian put forward in this article is to strengthen its intension and tap the latent power.  相似文献
