摘　　要： 从城镇体系规模结构方面,计算了长江三角洲地区城镇体系的首位指数、城市规模分形分布的分维数,并讨论了长江三角洲地区城镇体系的等级规模结构及其特点;从城镇体系空间结构角度,计算长江三角洲地区城镇体系中心城市吸引力的分维值和空间结构的关联维数,分析其分形结构特征.最后,提出长江三角洲地区发展的方向:在发挥江浙沪比较优势的基础上,进行合理分工,优势互补,最终实现区域经济一体化,形成区域整合优势,带动整个长江三角洲地区的全面发展. This paper studies the Urban system in Yantze delta using fractal theory. We figures out the primate city index in Yantze delta according to the town primacy rule of M. Jefferson, and then the town-size fractal dimension is worked out to discuss to the scale structure of the urban system in Yantze delta. In addition, spatial correlation dimension of the town-size distribution in Yantze delta is put forward to analyses the spatial structure of urban system. According to all these analyses it points out there are some deficiencies of the urban system in Yangtze delta, such as: (1)The scale distributing in Yangtze delta is primacy distributing; (2) Middle-small cities develop much slower than big cities; (3) The capacity of spatial interaction isn't strong enough. The paper puts forward the direction for developing the urban system in Yangtze delta: Realize the integration of regional economy, and speed up the development in Yangtzi delta.
