发布时间：2018-09-17 19:16
【摘要】：在界定空间极化概念的基础上,应用均匀度指数、基尼系数、崔王指数分析城市带内部要素集聚程度分异及空间极化格局,结论如下:(1)1990—2014年哈大巨型城市带要素集聚程度时空分异明显,"核心—边缘"结构逐步显现,城市带内部基于要素集聚程度的哈长与辽中南次区域逐渐发育;(2)城市带内部要素集聚存在显著的空间极化,空间极化的"四城市"格局已经形成;(3)城市发展内源力是哈大巨型城市带整体空间极化的主要影响因素,城市投资强度和经济发展水平对城市带空间极化格局演变的影响也较显著。城市投资强度与吸引力差异是哈长次区域空间极化分异的重要影响因素,而城市发展内源力是影响辽中南次区域空间极化的主要因素。
[Abstract]:On the basis of defining the concept of spatial polarization, this paper applies the evenness index, Gini coefficient and Cui Wang index to analyze the degree of concentration differentiation and spatial polarization pattern of urban inner elements. The conclusions are as follows: (1) from 1990 to 2014, the spatial and temporal differentiation of the concentration degree of elements in the mega-urban zone of Harbin is obvious, and the "core-edge" structure gradually appears. In the urban belt, based on the degree of factor agglomeration, Ha-Chang and the sub-region of central and southern Liaoning gradually develop. (2) there is a significant spatial polarization in the internal factor agglomeration of the urban belt. The "four cities" pattern of spatial polarization has been formed. (3) the endogenous forces of urban development are the main influencing factors of the overall spatial polarization of Harbin megacities. The influence of the intensity of urban investment and the level of economic development on the evolution of spatial polarization pattern of urban zone is also significant. The difference of urban investment intensity and attraction is an important factor in spatial polarization differentiation of Harbin and Changzhou sub-region, and the endogenous force of urban development is the main factor that affects spatial polarization in central and southern Liaoning sub-region.
