RESEARCH ON ANHUI JIANGHUAI URBAN AGGLOMERATION SPATIAL STRUCTURE OPTIMIZATION ACCORDING TO THE PROMOTION OF THE CITY-LEVEL
通过构建城市能级评价模型，分析安徽江淮城市群从雏形到快速成长阶段的空间特征，提出培育重要节点城市和E型空间优化路径，以融入长三角区域。
City-level reflects the city’s economic capacity of agglomeration and diffusion and the impetus of regional economic development.By the establishment of city-level and objective evaluation index system,based on the use of entropy method to determine index weight and builds the city-level evaluation model,from improving the aspects of the urban economy’s energy level,potential energy level and support level,analyzing Anhui Jianghuai urban agglomeration city-level’s variation spatial characteristics and development trend from prototype phase to the rapid growth stage.Based of it,the article proposed Jianghuai urban agglomeration the important node cities’ cultivation and optimal path according to the promotion of the city-level and the E-type space optimization model as the path of Jianghuai urban agglomeration integration into the Yangtze River Delta region.
