基于实际发生的信息流研究流空间网络格局是一种新的尝试。以吉林省县级以上地方为研究单元,以各地间固定电话通话时长为原始数据,采用主成分分析法、C-Value和D-Value层级分析法、优势流分析法、最小生成树法对吉林省流空间格局进行了分析。研究表明:吉林省流空间是以长春市为中心,长春市、延吉市、通化市、公主岭市为主导型城市,吉林市、白城市、白山市、辽源市、松原市、四平市为次级主导型城市,其他城市为从属型城市的层级化网络结构;行政区划在流空间格局中发挥基本的影响作用;以长春市为“单中心”的流空间特征明显,吉林省并无明显的次中心作用,长春市与吉林市流空间联系并不紧密,与传统认识和意愿有所不同;公主岭市和敦化市在吉林省流空间格局中占有重要地位,公主岭市倾向于融入长春城市圈,敦化市在吉林省东部空间网络格局中发挥了重要作用,两市的区域联通功能亟待挖掘;四平市和梨树县流空间联系紧密,适宜同城化发展。 |

Information communication is an important expression of interaction between two cities, and it is also a key element to build the city network. This study proposes to map the network structure of 'space of flows' based on the actual observed telecommunication flows, with Jilin Province as the case area. Specifically, the call durations via fixed- line telephone are employed to measure the information flows occurred between cities. The cities at the county level or above are treated as research units. To be reliable, a synthetic method composed of principal component analysis, C-Value and D-Value hierarchy analysis, dominant flow analysis, the minimum spanning tree method is utilized to map out the structure. The research reveals the following aspects. (1) The 'space of flows' in Jilin Province is a hierarchical network, which centers on Changchun. In this network, Changchun, Yanji, Tonghua and Gongzhuling are the 1st-level leading cities; Jilin, Baicheng, Baishan, Liaoyuan, Songyuan and Siping are 2nd-level leading cities, and the other cities in Jilin are subordinate cities. (2) Administrative division plays a fundamental role in the formation of the current pattern. (3) Changchun is a unique center, but on the contrary to our previous understanding, Jilin is not that 'centric', and the interaction between Changchun and Jilin is not that strong either. (4) Surprisingly, the two cities of Gongzhuling and Dunhua at the county level, play important roles in the network of 'space of flows'. Gongzhuling tends to be blended in the Changchun metropolitan area, and Dunhua becomes a key node in the eastern Jilin. The regional connectivity functions of the two cities need to be improved. (5) Siping and Lishu, have strong interaction with each other, and are supporting a further integration strategy of the two neighboring cities. |
