摘要：

开放条件下，“全球地方”作用深刻影响着区域城镇体系，沿江发达地区表现尤其典型。基于分形的相关理论和方法，以2006年为时空断面，对江苏沿江地区城镇体系的空间分布进行实证研究。结果表明：（1）区域城镇规模等级结构服从Zipf定律，首位城市南京在区域城市体系中的垄断性相对较强，但并非处于绝对垄断地位；（2）空间关联维数显示，沿江地区城镇体系的交通网络通达性优良，各城镇间联系紧密；（3）根据分维数和无标度区分析，三大城市群中，宁镇扬城市群分形发育最好，苏锡常次之，通泰城市群分形发育最差；（4）扬州、镇江、南京和苏州的城镇集聚程度较高，分形发育较为成熟；南通、泰州、无锡和常州的集聚程度均较低，分形结构不佳。扬州在区域城镇体系中分形发育最为完善，中心性最好，历史上形成的这种空间格局至今没有变化.

Abstract:

Globallocal force has made a profound impact on the regional urban system under opening condition,especially for the developed areas along the river.The paper gave a study on urban system along the Yangtze River based on Fractal Theory in Jiangsu Province in 2006.Four characteristics have been summarized:(1) The size of the hierarchical structure of the urban system comply with Zipf's Law,and the primary city of Nanjing is not in a position of absolute monopoly in the regional city system.(2) It has been proved that the regional cities and towns are in close cont〖JP2〗act and has excellent transport network accessibility,〖JP〗according to the spatial correlation dimension.(3) The fractal structure of Yangzhou,Zhenjiang, Nanjing and Suzhou cities is much better,while that of Nantong,Taizhou,Wuxi and Changzhou is poor.(4)The fractal structure of Yangzhou of regional urban system is most perfect,and the spatial pattern has not changed.

Key words: fractal theory/ urban system/ spatial structure/riverside area along the Yangtze River in Jiangsu Province
