长三角城市群城镇化质量测度及其空间格局分析

Analysis of measurement and spatial pattern of urbanization quality in the Yangtze River Delta

选取2005、2010、2014三个时间节点,运用熵值法和聚类分析法对长三角城市群进行城镇化质量测度与空间格局分析。研究结果表明,长三角城镇化质量在三个时间段内都处于上升趋势。以上海为核心,城镇化质量较高的区域大都集中在省会城市南京、杭州及其邻近城市苏州、无锡等,大致呈东西方向带状分布;城镇化质量中等的区域如常州、绍兴、嘉兴等,大致呈点状分布,大都围绕分布在城镇化质量较高区域周围;城镇化质量较低的区域大都集中在长三角城市群东北部,南通、泰州、湖州等市,其空间格局变动较为稳定。

Taking2005、2010and2014as the three time node,the urbanization quality in the Yangtze River Delta was measured,and the spatial pattern of its evolution was analyzed by using entropy method and cluster analysis method.The results showed that the level of urbanization quality in the Yangtze River Delta is in an upward trend in the study period.The urbanization quality of the Yangtze River Delta can be classified into4category-areas according to clustering analysis:lowquality area,medium-quality area and high-quality area.Taking Shanghai as the center,high-quality areas of urbanization were mostly concentrated in the capital city of Nanjing,Hangzhou and the nearby city of Suzhou,Wuxi and so on,which presented from east to west zonal distribution.Medium quality of urbanization area such as Changzhou,Shaoxing,Jiaxing and so on,tend to be a point distribution,which were mostly around the regions with high quality.Low-quality areas of urbanization were mostly concentrated in the northeastern part of the Yangtze River Delta,such as Nantong,Taizhou,Huzhou and so on.Spatial pattern of low-quality areas was more stable in three time node.The paper provided some countermeasures and suggestions improving the quality of urbanization.
