省域不同经济发展水平地区城镇空间形态研究——以江苏为例

Research on Urban Spatial Form in Provincial Areas with Different Levels of Economic Development:A Case Study of Jiangsu Province

针对经济发展水平不同地区采取不同城镇发展模式,实现区域统筹发展已成为各省关注的重点。该文以江苏省苏南、苏中、苏北地区为例,通过对经济发展水平与城镇空间形态特征差异的研究,苏北以徐、淮、盐、连等大城市主导点状集中,苏中以宁通交通轴主导的带状聚合,苏南以南京、苏锡常城市区域主导的网状集聚,苏南、苏中以沿江,苏中、苏北以沿海港口为纽带形成新的城市带。分析动力机制,提出省域不同经济水平地区的城镇空间优化措施和政策建议,统筹区域发展苏南重点在于推进区域一体化,苏中重点在于建设沿江沿海城镇发展带;苏北重点在于建设中心城市。

Different regions take different urban development models according to different levels of economic development to realize the regional overall development ,which has already become main concern of provinces. In this paper,taking the southern, central, and northern areas of .liangsu province as an example, it studies the differences in urban morphological characteristics and the levels of economic development： pointlike concentration led by large cities, such as Xuzhou, Huaian, Yancheng, Lianyungang in northern ,liangsu; ribbon concentration led by Nanjing-Nantong traffic axis in central Jiangsu; mesh concentration led by Nanjing metropolitan and Su-Xi-Chang metropolitan in southern Jiangsu; southern, central to the Yangtze River, central, north to the coastal ports as a link to form new city zones. Analyzing the dynamic mechanism,we propose distinguishing urban space optimization measures and policy recommendations to regions in different economic development levels to realize the regional overall development： the focus of the south is to promote regional integration; the focus of the centre is to construct the urban development belts along the Yangtze River and the coast; the focus of the north is to strengthen the central citis construction.
