| 摘 要： | 基于滑动窗口的局部分维分析方法--元分维模型,采用2005年江苏省城镇基础数据,对江苏省1 850个城镇及街道办的空间均衡程度进行定量测度,结果表明:①江苏城镇体系空间均衡程度差异明显,自南向北存在一定程度的空间梯度递减,其中江苏南部城镇分布最为密集且较为均衡,江苏中部次之,而江苏北部除徐州市区外.均衡程度较低;②江苏城镇分布上东部比西部均衡;③江苏城镇轴线集中发展的分布特征突出,沿长江分布的无锡、常州、苏州、镇江、扬州、泰州、南通、南京8个地区城镇分布密集,且均衡程度较高;④城镇体系的空间均衡程度与城市化水平基本一致.实验证明,元分维模型可以用于定量分析特定尺度下的城镇局部空间均衡程度的差异.

| Abstract: | The spatial pattern of urban system in the result of the location selection is formed mainly through the economic activities and the population migration in history.It is an important part of the study of the urban system taking towns in Jiangsu Province as a point in a geographical space in order to discover the spatial distribution of the towns and to analyze the formation of the internal mechanism of this type.There are four methods of the urban system's spatial structure research widely used currently.T... |
