【摘要】：信息技术的应用与社会信息技术的传输,使大量的要素(人流、物流、信息流)在城市群空间内集聚与扩散,加密城市群空间内城市联系。在基于公路运输、普通列车、高速列车以及百度指数4个要素的综合分析基础上,对长三角城市群"空间流"网络结构特征进行探析。研究结果表明:(1)长三角城市群区域内城市联系虽具备了网络化规模,但城市间的联系不均衡,以上海、南京、杭州等城市为多中心的协调网络发展格局特征明显;(2)长三角城市群16个核心城市"空间流"特征呈现三角形网络结构,其三角形的顶角分别由上海(沪)、南京(宁)与杭州(杭)3个核心节点城市构成。在空间结构内部,形成若干次级城市网络连线;在空间分布上,北翼网络化程度较高于南翼线性联系程度,区域联系强度以"沪—宁"、"沪—杭"沿线向两侧递减;(3)上海、南京、杭州、苏州、无锡5个核心城市排名处于网络中心的前列,扬州、南通、泰州、舟山等周边城市相对靠后,这与区域经济发展过程的"吸虹效应"有关,随着区域经济一体化程度的加深,中心城市会向周边地区提供服务与经济辐射,完善整个长三角城市群网络体系。
[Abstract]:The application of information technology and the transmission of social information technology make a large number of elements (human flow, logistics, information flow) gather and spread in urban agglomeration and encrypt urban connections in urban agglomeration space. On the basis of the comprehensive analysis of 4 elements based on highway transportation, ordinary trains, high-speed trains and Baidu index, the "space" of the Yangtze River Delta city group is "space" The research results show that: (1) although the urban links in the urban agglomeration of the Yangtze River Delta have network scale, the relationship between cities is not balanced, and the multi center coordinated network development pattern of Shanghai, Nanjing, Hangzhou and other cities is obvious; (2) the spatial flow of 16 core cities in the Yangtze River Delta city group is characterized by the characteristics of "space flow" The triangle network structure is composed of 3 core node cities of Shanghai (Shanghai), Nanjing (Ningxia) and Hangzhou (Hangzhou). In the space structure, some secondary urban network connections are formed. In space distribution, the network level of the north wing is higher than the south wing linear connection degree, and the regional connection intensity is "Shanghai to Nanjing", "Shanghai Hangzhou". Along the two sides, (3) the 5 core cities of Shanghai, Nanjing, Hangzhou, Suzhou and Wuxi rank in the forefront of the network center, Yangzhou, Nantong, Taizhou and Zhoushan are relatively backward. This is related to the "siphon effect" in the regional economic development process. With the deepening of regional economic integration, the central city will provide the surrounding areas. Service and economic radiation, and improve the whole Yangtze River Delta urban agglomeration network system.
