土地利用效益与新型城镇化耦合协调性分析——以长三角城市群41个城市为例

Analysis on coupling coordination between Land Use Efficiency and New Urbanization——Taking 41 cities in the Yangtze River Delta urban agglomeration as an example

该研究以长三角城市群41个城市为对象,通过耦合协调模型和ArcGIS软件分析土地利用效益与新型城镇化耦合协调度时空演变特征。结果表明:土地利用效益和新型城镇化水平均稳步上升;上海土地利用效益和新型城镇化水平在长三角城市群处于领先地位;3个省份中江苏土地利用效益和新型城镇化水平最高,浙江和安徽次之;土地利用效益和新型城镇化耦合一直处于拮抗阶段;耦合协调度不断提升,空间上呈现以“上海—南京—杭州—合肥”为中心并逐步向外围城市辐射的趋势。

This paper takes 41 cities in the Yangtze River Delta urban agglomeration as the research object and uses coupling coordination model and ArcGIS software to analyzes the spatial and temporal evolution characteristics of land use efficiency and new urbanization coupling coordination degree.The results showed that land use efficiency and the level of new urbanization are steadily rising;Shanghai’s land use efficiency and the level of new urbanization in the Yangtze River Delta urban agglomeration in a leading position;among the three provinces,Jiangsu has the highest land use efficiency and new-type urbanization level,followed by Zhejiang and Anhui.The coupling of land use efficiency and new urbanization is always in the antagonistic stage.The coupling coordination degree is constantly improving,and the space presents a trend of taking‘Shanghai-Nanjing-Hangzhou-Hefei’as the center and gradually radiating to the peripheral cities.
