摘要:
城市群多中心发展可以缓解核心城市过于集聚、中小城市发育不足的问题,通过培育城市群多中心,能够有效促进城市群内其他城市的发展,分担核心城市的部分功能.基于尼克·格林多中心研究方法,选取运输快捷、花费时间少、乘客选择意愿高的高速动车(G)、动车组(D)、城际高速(C)、直达特快(Z)、空调特快(T)等快速通勤列车,以成渝城市群内部各城市间铁路日均往来车次作为基础数据,计算分析成渝城市群功能多中心度,并与欧洲8城市区域、长三角城市群、珠三角城市群进行比较.研究发现:①成渝城市群中成都市和重庆市主城区仍然是发展重心,在双核外,德阳、遂宁、万州、涪陵、长寿等城市具有成为新的区域多中心的潜力;②四川省南部自贡、泸州和重庆市东部忠县、黔江等12个地级市、市辖区仍然没有铁路客运的往来,使得城市群难以发挥完全的功能多中心效应;③成渝城市群功能多中心度偏低,属于功能多中心发展的初级阶段,其发展水平不如已经发展到典型功能多中心的长三角城市群、珠三角城市群.

Abstract:
The model of multi-centered development can alleviate the problems of urban sprawl of the metropolitan area and insufficient development of secondary cities in urban agglomeration. Based on the Nick Green multi-centered research method, this paper adopts high-speed trains (G), EMUs (D), intercity expressways (C), direct express (Z), and air-conditioning express trains (T) as the fast rail transportation to calculate and analyze multi-centered degree of function in Chengdu-Chongqing urban agglomeration. This paper also makes a comparison with European urban agglomerations, Yangtze River Delta urban agglomerations, and Pearl River Delta urban agglomerations. The results show that both Chengdu and Chongqing metropolitan areas are still the foci in Chengdu-Chengdu urban agglomeration. Deyang, Suining, Wanzhou, Fuling, Changshou and some other cities have the potential to become sub-centers outside the dual-core. There are still no fast railways in 12 prefecture-level cities and municipal districts, such as Zigong and Luzhou in the southern part of Sichuan Province and Zhongxian and Qianjiang in the eastern part of Chongqing, which makes it difficult for urban agglomeration to exert full function and multi-centered effects in these areas. The multi-centered function in Chengdu-Chongqing urban agglomeration is in the primary stage of function multi-centered development, compared to the situation in Yangtze River Delta and Pearl River Delta, which have developed into metropolitans with typical multi-centered functions.
