城市群网络空间交互情景的场源场强分析法

区域网络空间交互已逐渐成为地理学热点研究问题。本文将由城市群形成的城市化区域抽象为地理空间数据场,以城市为场源、城市间的交互作用为场强度量,构建了基于地理空间数据场的城市间多向网络交互情景分析模型。以武汉城市圈为典型区,以城市圈5年时点数据为基础,分析了城市多向网络交互作用及其在区域一体化发展过程中的动态变化。结果表明:武汉城市圈内一核众弱空间格局明显,区域整体交互差异显著不均;2006年后,城市交互强度上升速率有了较大提升,武汉城市圈政策对城市网络交互情景的影响初步显现。

A Field Source-strength Method for Interaction Scenario in Network Space of Metropolitan

With the collaborative development of region ,spatial interaction has become a hotspot issue in geography research .A scenario analysis model of urban multidimensional interaction was proposed based on geography spatial data field .Where the urban clustering area was viewed as a geography spatial data field .While the intercity spatial interactions were considered as field strength in the model .Then Wuhan metropolitan area was taken as a case to study intercity spatial interaction and its dynamics .The results indicatesthattheintercityspatial interactionisinfirmnessanditsspatial patternshowing“onenuclear and multitude weak”,eastern interaction stronger than the west .Since 2006 ,effected by the policy of“1+8 City Circle of Wuhan”,the interaction has been reinforced and the integration process has been promoted effectively in recent years .
