【摘要】：信息技術(shù)的應(yīng)用與社會(huì)信息技術(shù)的傳輸,使大量的要素(人流、物流、信息流)在城市群空間內(nèi)集聚與擴(kuò)散,加密城市群空間內(nèi)城市聯(lián)系。在基于公路運(yùn)輸、普通列車、高速列車以及百度指數(shù)4個(gè)要素的綜合分析基礎(chǔ)上,對(duì)長(zhǎng)三角城市群"空間流"網(wǎng)絡(luò)結(jié)構(gòu)特征進(jìn)行探析。研究結(jié)果表明:(1)長(zhǎng)三角城市群區(qū)域內(nèi)城市聯(lián)系雖具備了網(wǎng)絡(luò)化規(guī)模,但城市間的聯(lián)系不均衡,以上海、南京、杭州等城市為多中心的協(xié)調(diào)網(wǎng)絡(luò)發(fā)展格局特征明顯;(2)長(zhǎng)三角城市群16個(gè)核心城市"空間流"特征呈現(xiàn)三角形網(wǎng)絡(luò)結(jié)構(gòu),其三角形的頂角分別由上海(滬)、南京(寧)與杭州(杭)3個(gè)核心節(jié)點(diǎn)城市構(gòu)成。在空間結(jié)構(gòu)內(nèi)部,形成若干次級(jí)城市網(wǎng)絡(luò)連線;在空間分布上,北翼網(wǎng)絡(luò)化程度較高于南翼線性聯(lián)系程度,區(qū)域聯(lián)系強(qiáng)度以"滬—寧"、"滬—杭"沿線向兩側(cè)遞減;(3)上海、南京、杭州、蘇州、無(wú)錫5個(gè)核心城市排名處于網(wǎng)絡(luò)中心的前列,揚(yáng)州、南通、泰州、舟山等周邊城市相對(duì)靠后,這與區(qū)域經(jīng)濟(jì)發(fā)展過(guò)程的"吸虹效應(yīng)"有關(guān),隨著區(qū)域經(jīng)濟(jì)一體化程度的加深,中心城市會(huì)向周邊地區(qū)提供服務(wù)與經(jīng)濟(jì)輻射,完善整個(gè)長(zhǎng)三角城市群網(wǎng)絡(luò)體系。
[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.
