浙江省城市化和城市土地集约利用的时空耦合关系

基于城市化与城市土地集约利用的综合评价指标体系,对浙江省城市化水平和城市土地集约利用进行测度,然后构建城市化水平和城市土地集约利用度的耦合协调发展度模型,采用ArcGIS10.2进行时空差异分析。结果表明:各个城市的城市化和城市土地集约利用耦合协调度都在逐年优化,协调水平较好,城市发展呈现上升态势;两者耦合协调发展水平空间差异显著,呈现出片状分区集聚的特征。北部耦合协调度高,处于协调期,南部呈东西分化状态,其中西部衢州、丽水两市处于拮抗期,东部城市大都处于磨合期。

Research on Spatio-temporal Coupling between Urbanization and Intensive Urban Land Use in Zhejiang Province

Based on the compressive evaluation index system of urbanization and intensive urban land use,this paper evaluates the level of urbanization and intensive urban land use in Zhejiang province and constructs the coupling coordination model,then analyses the spatio-temporal disparities with ArcGIS10.2.The results show that the coupling coordination level of all cities tends to optimization and is favor of the cities' development;in the meantime,there is a significant difference in the spacial distribution and presents the trend of flake partition clustering.In addition,the coupling coordination level for the cites in north part are in high level and coordination stage,but the cities in south are different,such as Quzhou and Lishui in the south-west part are in antagonism stage,the cities in the south-east are almost in compromise stage.
