成渝城市群空间结构的引力模型分析
|
摘要
通过引力模型,对成渝城市群城市间的引力进行测算,研究成渝城市群的空间结构.结果表明:成渝城市群中引力最大的城市为重庆市主城区,36个城市中有21个城市与重庆主城区的引力值最大,仅有6个城市与成都市的引力值最大,而且四川部分的城市引力明显低于重庆部分城市间的引力值,成渝城市群东西发展不平衡的现象明显.为了促进成渝城市群的协调发展,应增强重庆主城区和成都市双核辐射带动作用,加强德阳市、绵阳市、南充市、泸州市、自贡市和万州区的经济支撑作用.
The gravitation of Cheng-Yu urban agglomeration was calculated for studying its spatial structure by gravitation model. The results show that the most gravitational city in Cheng-Yu urban agglomeration is the main urban area of Chongqing. Among those 36 cities, 21 of them have the largest gravitation value concerned with Chongqing.s main urban area. Only6 of them have the highest gravitation value concerned with Chengdu, and the gravitation of the cities in Sichuan is obviously lower than that of Chongqing. The imbalance between the east and west of Cheng-Yu urban agglomeration is obvious. In order to promote its coordinated development, the dual-nuclear radiation function of Chongqing.s main urban area and Chengdu should be strengthened, and the economic support role of Deyang city, Mianyang city, Nanchong city, Luzhou city,Zigong city, and Wanzhou district should be strengthened too.
