摘　　要：以中原经济区为研究区域,选取2000、2003、2006和2009年4个时间截面,采用城市流强度模型对中原经济区28个城市的城市流强度进行了测度。根据计算结果,运用Q形聚类法,将中原经济区28个城市的城市流强度划分为15种类型,同时,进一步分析了中原经济区城市流强度的时空演变规律。结果表明:①中原经济区尚处于经济发展的初级阶段,区内各部门的外向服务能力不强,整体的集聚和辐射能力较弱,空间联系较为松散;②随时间变化,城市流强度的绝对差异在增大,相对差异在减小,区内城市发展水平和整体实力相差较大;③郑州居中原经济区城市流强度高值区中心,且郑州与区内外围城市的城市流梯度差不断缩小,溢出效应开始显现;④空间格局变化较小,且基本呈现北高南低、东高西低的分布格局;⑤特殊的区位优势对区域内城市流强度的影响显著。The thesis takes the Economic Zone of central China as the study area, choosing the years 2000, 2003, 2006 and 2009 as the time sections. The study applies the degree of urban flow as the model to measure 28 cities of the Economic Zone of central China. The paper then divides the degree of urban flow of the 28 cities into 15 categories according to the results deriving from the Q method of clustering. Meanwhile the spatial and temporal evolution rules of the degree of urban flow are analyzed. The results show that the central China region still remains at the early stage of development. Each department has relatively weak external service ability, small overall agglomeration and radiation capacity and loose spatial association. The absolute difference of urban flow degree is growing and the relative difference is decreasing with time, and great gaps exist among the cities in terms of the development level and overall ability. As the center of the high-degree urban flow in the central China Economic Zone, Zhengzhou is reducing the gradient difference with the outer cities of the region and the overflow effect is emerging as the core city of the Economic Zone. In terms of the spatial evolution, there is an overall stability in the spatial pattern, with north and east higher and south and west lower. Regional advantage has a great impact on the degree of urban flow, while the higher degree of urban flow of Xuzhou is closely related to its special developing environment.
