城市土地利用效益与城市化耦合协调发展研究——以陕甘宁27个城市为例

Coupling Coordination Degree of Urban Land Use Benefits and Urbanization——A Case of 27 Cities in Shaanxi-Gansu-Ningxia Border Region

对城市土地利用效益系统和城市化系统共选取30个指标,构建城市土地利用效益与城市化综合评价指标体系。采用熵权法测度两个系统的发展水平,在此基础上,运用耦合协调发展度模型,对2003年,2006年,2009年及2012年4个时段陕甘宁27个城市土地利用效益与城市化耦合协调发展进行研究。结果表明:城市土地利用效益偏低,远远滞后于城市化,制约城市化健康发展;城市土地利用效益与城市化耦合协调发展大多处于拮抗阶段且耦合协调发展度呈现出显著的动态波动特征,但自2006年起呈良性发展态势并保持螺旋上升;耦合协调发展度在空间上表现为先相似属性集聚分布后随机分布的特征,由不均衡发展状态逐渐转变为良性发展状态的趋势。

Thirty indicators are selected by urban land use benefits and urbanization system, and based on the construction of urban land use benefits and the comprehensive evaluation index system of urbanization, the entropy weight method was adopted to measure the development level of the two systems, and the coordina- ted development degree of model was used to investigate the coupling coordination development degree of about several 27 cities in the four periods of 2003, 2006, 2009 and 2012. The conclusions are as followings. The urban land use benefits were low, far lagging behind urbanization, preventing urbanization healthy development; urban land use benefits and most of the coupling degree of coordinated development of urbani- zation showed the characteristics of dynamic fluctuation significantly at the stage of antagonism. However, there was the benign development trend and keeping spiral since 2006; coupling degree of the coordinated development in space presented the similar attribution with concentration distribution first and then showed the random distribution characteristics, varying from the unbalanced development state gradually to the state of the benign development trend.
