摘　　要：文章旨在探讨江苏省城镇化发展的空间结构特征,为优化区域协调发展提供参考。采用引力模型和断裂点公式作为主要研究方法,分析了江苏省13个地级市间的引力值、断裂点距离及空间集聚效应。研究表明:江苏省内城市间引力值差异显著,苏南地区引力较强,形成了南京都市圈、苏锡常都市圈、淮海经济区的城镇化发展核心区域;江苏省城市间存在明显的屏蔽效应,导致部分城市发展受到抑制;江苏省城镇化发展在空间上呈现不均衡分布,高值区域主要集中在苏南地区,而苏北地区则多为低速增长区。This paper aims to explore the spatial structure characteristics of urbanization development in Jiangsu province,providing a reference for optimizing regional coordinated development.By employing the gravity model and breakpoint formula as primary research methods,the gravitational values,breakpoint distances,and spatial agglomeration effects among 13 prefecture-level cities in Jiangsu province were analyzed.The study reveals that there are significant differences in gravitational values among cities in Jiangsu province,with stronger gravity observed in the southern Jiangsu region,forming core areas of urbanization development such as the Nanjing Metropolitan Circle,Su-Xi-Chang Metropolitan Circle,and the Huaihai Economic Zone.There is a notable shielding effect among cities in Jiangsu province,inhibiting the development of certain cities.The urbanization development in Jiangsu province exhibits an uneven spatial distribution,with high-value areas mainly concentrated in southern Jiangsu region,while northern Jiangsu region is characterized by low-growth areas.
