成渝城市群新型城镇化发展协调性研究

新型城镇化是人口、土地、经济、生态、社会5大城镇化子系统的协调推进,运用协调度模型、探索性空间数据分析和障碍度模型,判别成渝城市群城镇化发展的协调性。结果表明:成渝城市群城镇化综合水平整体不高,其均值和标准差随时间增大,各区域间差异显著;子系统的发展在空间上呈现非均衡性特征,人口城镇化分异程度始终最高但空间分异不断缩小,社会和经济城镇化的空间分异逐渐增大,土地和生态城镇化的空间分异不断缩小。成渝城市群城镇化协调度总体呈现递增态势,空间分异特征较明显但不断缩小;城镇化协调度相似地区在空间上呈现强集聚状态,成都市、德阳市、眉山市、南川区、綦江区始终为热点区域,渝东及渝东南始终为冷点区域,热点区和冷点区比重逐渐增加。

Coordination Development of New-type Urbanization in Chengdu-Chongqing Urban Agglomeration

New-type urbanization is the coordinate of population, land, economic, ecological and social subsystem of urbanization.Using the coordination degree model, exploratory spatial data analysis and the disorder degree model, discriminant Chengdu-Chongqing urban agglomera-tion of urbanization development coordination.The results showed that, the level of urbanization among Chengdu-Chongqing urban agglomera-tion was not too high, mean and standard deviation of urbanization level increases with time and the spatial difference was significant .The de-velopment of urbanization subsystem was non-equilibrium.The spatial difference of demographic urbanizationis was always highest but shrink-ing, and the spatial difference of economic urbanization and social urbanization increase gradually, the spatial difference of land urbanization and ecological urbani-zation keeps reducing.The coordination degree of urbanization in Chengdu-Chongqing urban agglomeration keeps in-creasing, spatial variation was obvious but shrinking.The similar region of urbanization coordination shows a strong aggregation state .The hotspots of urbanization co-ordination were centralized in the regions of Chengdu, Deyang, Meishan, Nanchuan and Qijiang, and the coldspots were centralized in the regions of eastern Chongqing and southeast Chongqing .The hotspot and coldspot regions had been increased gradually .
