江苏省人口、土地及经济城镇化的耦合协调性及时空演变特征

为给江苏省城镇化的健康发展提供参考,采用耦合协调度模型和功效函数测度江苏省13个地级市2006—2014年人口、土地及经济城镇化发展水平,并从时空角度探讨其协调性分异及时空演变特征。结果表明:江苏省各地市城镇化发展水平呈逐年上升趋势,整体而言,土地城镇化水平高于人口、经济城镇化水平;人口、土地、经济城镇化耦合协调度整体水平较低,呈明显的空间分异和块状聚类特征。

Coupling Harmony and Spatial-temporal Evolution Characteristics of Population Urbanization,Land Urbanization and Economy Urbanization in Jiangsu

The development level of population urbanization, land urbanization and economy urbanization in 13 prefecture-level cities during 2006~2014 is measured by the coupling harmony model and effect function analysis and the harmony variation and spatial-temporal evolution characteristics are discussed from an spatial-temporal angle to provide a reference for healthy development of urbanization in Jiangsu Province.Results: The urbanization development level of 13 prefecture-level cities presents a rising trend year by year and the land urbanization level is higher than the level of population urbanization and economy urbanization on the whole.The overall coupling harmony level of population urbanization, land urbanization and economy urbanization is lower, which presents an obvious characteristics of spatial variation and massive cluster.
