京津冀地区城市土地集约利用与城镇化耦合协调关系研究

Coupling Coordination Between Urbanization and Intensive Urban Land Use in Beijing-Tianjin-Hebei Area

以京津冀地区作为研究区域,建立城市土地集约利用指标体系与城镇化指标体系,采用均方差权值法,并建立耦合协调模型,计算2011年13个地级以上城市的土地集约利用和城镇化指数及二者的耦合度和协调发展度。按照耦合协调度的高低将13个城市划分为4大类;每个大类内部再按照城市土地集约利用与城镇化指数的关系,分为城市土地集约利用滞后和城镇化滞后的2个亚类。结果表明:京津冀地区城市土地集约利用和城镇化之间关系密切,二者相互作用,但并非同步发展;城市土地集约利用程度与城镇化耦合程度基本上处于颉颃阶段,耦合协调度水平总体不高,区域差异明显。

Beijing-Tianjin-Hebei Area was taken as the study example to present the indicator system（IS）of urbanization and urban-land intensive utilization.We used the mean squared weighted deviation method and built a coupling coordination model,and computed the IS of urbanization and urban-land intensive utilization as well as their coupling degree and coordination development degree for 13 cities at prefecture level or beyond in Beijing-Tianjin-Hebei Area.The 13 cities were divided into 4major categories according to the level of the coupling coordination,followed by 2subclasses of urban-land intensive utilization delay and urbanization delay on the basis of the internal relationship between the urban land intensive utilization and urbanization index.The results showed that there was a close relationship between the urbanization and urban-land intensive utilization,which was interaction but beyond the simultaneous development.The degree of urban-land intensive utilization and the coupling degree of urbanization were basically at the stage of equality,together with a lower level of urban coordination development in general and the remarkable difference between regions.
