摘要
土地集约利用与城市化耦合协调性程度共同影响着城市系统的发展状态,准确把握二者之间的耦合协调性时空特征,对制定城市土地利用政策和城市化发展战略具有重要的参考价值。在城市土地集约利用和城市化内涵解析的基础上,建立了评价指标体系,以河南省地级市为例,采用2006年、2009年、2012年指标数据,运用熵值法和耦合协调模型,对城市土地集约利用与城市化耦合协调性进行了评价。结果表明:(1)城市土地集约利用出现波动,但城市化综合指数稳步上升,二者之间的相对发展关系总体上由超前型向同步型发展;(2)城市耦合协调度和发展度均呈上升趋势,但空间分布特征差异明显;(3)城市耦合协调发展阶段总体上由拮抗期经磨合期向协调期发展。最后,采用2012年数据,依据城市耦合协调类型划分标准,将河南省划分为4种耦合协调类型,即磨合期V、磨合期Ⅵ、协调期Ⅷ和协调期IX。
The coupled coordination degree of land intensive utilization and urbanization always influences the development of urban system, so it is very important to grasp the coupled coordination characteristics of the two aspects. Based on the relation between intensive land use and urbanization, the evaluation index system of intensive land use and urbanization was established for prefecture-level cities in Hernan Province. Entropy value method and coupling coordination model were used to analyze index extracted from the data of the years of 2006, 2009 and 2012, and the coupled coordination between intensive land use and urbanization was evalu- ated. The results showed that： （1） the fluctuation change of intensive urban land utilization was obvious, but the urbanization comprehensive index was steadily rising, the intensive use of urban land, which previ- ously preceeded the development of urbanization, was recently synchronized with urbanization; （2） the over- all urban coupled coordination degree and development level rose with obvious differences between areas; （3） urban areas in Hetnan Province had experienced three stages, namely, the antagonism, the running in period and the coordination period. Finally, according to the criterion defined for the coupled coordination types, cities in Hernan Province were divided into four types such as initiation V, initiation VI, coordinated stage Ⅷ, and coordinated stage IX.
