【摘要】：引入人口重心、GIS网络分析及时序全局主成分分析法对传统引力模型进行修正,由此测算城市潜力值,以定量测度2002~2013年武汉城市圈城市空间相互作用强度,并结合IDW空间插值法和CTCSTP算法揭示出其时空演变规律。结果表明:(1)武汉城市圈各城市与其他城市间相互作用总强度总体呈增长趋势,其中武汉市增幅远高于其他城市,其与孝感-鄂州-黄石形成显著的轴线式发展格局,其余城市始终为空间联系弱区地带。(2)武汉市辐射带动作用日趋强劲,辐射范围逐年扩大并呈现一定的"圈层式"分布,其余城市辐射带动作用较弱,仅孝感市略显对外辐射趋势。(3)整个区域的空间相互作用表现出显著的"西南部低、北部高、东部适中"的空间分异特征,且其重心由南向北转移明显,区域发展不均衡特性显著。
[Abstract]:The introduction of population gravity center, GIS network and time sequence analysis of principal component analysis to modify the traditional gravity model method, which estimates the potential value to measure the city, 2002~2013 Wuhan city circle city spatial interaction strength, combined with IDW spatial interpolation method and CTCSTP algorithm to reveal the evolution of the time. The results showed that: (1) Wuhan city circle of the city and other city interaction between the total strength of the overall growth trend, of which Wuhan city is much higher than other city, the Xiaogan - Ezhou - Huangshi was formed the axis development pattern, the rest of the city is always weak spatial contact zone. (2) Wuhan City, the increasingly strong leading role of radiation, radiation the scope has expanded each year and show a "circle" distribution, the rest of the city leading role is weak, only Xiaogan city slightly external radiation trend. (3) the regional spatial interaction performance There are significant spatial differentiation characteristics of "low southwest, high north and moderate East", and the center of gravity is shifted from south to north, and the unbalance of regional development is remarkable.
