摘　　要：在“东北地区再振兴”背景下,研究现实与虚拟流视角下的东北地区城市空间网络特征对于认识和重塑东北地区经济社会空间结构具有重要意义。利用经济、普列、高铁、信息等联系强度模型和社会网络分析指标探讨东北地区城际多维要素流强度和城市空间网络特征,结果表明:①东北地区城市具备空间网络化发展规模,形成以沈阳、哈尔滨、长春、大连为核心,吉林、鞍山、齐齐哈尔为副核心,哈尔滨—大连一轴,辽宁省子群、吉林省子群、黑龙江省西部子群、黑龙江省东部子群、赤峰—通辽、乌兰浩特—白城、伊春—黑河等关系对的“四核、三副、一轴、七群”空间结构。②多维要素流影响下的辽中南城市群一体化态势比哈长城市群强烈,沈阳、哈尔滨、长春、大连的流量最强,哈尔滨省内联系对象为齐齐哈尔、大庆,长春省内联系对象为吉林,沈阳省内联系对象为大连、本溪、丹东,大连省内联系对象为沈阳、丹东、营口。③东北地区“T”型轴带有向哈(尔滨)大(连)单轴发展的趋势,综合流呈沿哈大轴带向东西两侧衰减的“核心—边缘”格局。其中经济流呈辽宁省向吉林省,继而向黑龙江省与蒙东区由南至北的衰减格局;普列流呈以哈大与滨洲铁路为轴带,并向两侧弱化的空间格局;高铁流呈沿哈大主轴带、长珲与哈齐次轴带向两侧非对称的递减格局;信息流呈“四核心、四边缘”的格局特征。Under the background of"Revitalization of Northeast China",it is of great significance to study the urban spatial network characteristics from the perspectives of reality and virtual flow in Northeast China.This paper studied the intercity element flow intensity and the urban spatial network characteristics in Northeast China from the perspectives of economic flow,general-speed train flow,high-speed rail(HSR)flow and information flow.The results are as following:1)Northeast China’s cities display the network development trend,which is composed of four centers,three subcenters,one axis and seven subgroups.Shenyang,Harbin,Changchun and Dalian are the network centers,while Jilin,Anshan and Qiqihar are the sub-centers.One axis is formed by Harbin and Dalian.Seven subgroups are distributed in Liaoning Province,Jilin Province,the east and west of Heilongjiang Province,Chifeng-Tongliao,Ulanhot-Baicheng,Yichun-Heihe.2)Under the influence of multi-dimensional flow,the integration of urban agglomeration in central-southern Liaoning is stronger than that in Harbin-Changchun.Shenyang,Harbin,Changchun and Dalian have the strongest flow in Northeast China.Harbin has good contact with Qiqihar and Daqing in Heilongjiang Province.Changchun has good contact with Jilin City in Jilin Province.Shenyang has good contact with Dalian,Benxi and Dandong in Liaoning Province.Dalian has good contact with Shenyang,Dandong and Yingkou in Liaoning Province.3)It’s found that the Harbin-Dalian line has become the main"corridor"in Northeast China and presents the core-periphery pattern in term of comprehensive flow.The economic flow shows the continuous attenuation pattern from Liaoning to Jilin,then to Heilongjiang and the east of Inner Mongolia.The general-speed train flow shows the attenuation trend centered on the railways of Harbin-Dalian and Harbin-Manzhouli.The HSR flow shows the asymmetrical decreasing trend along the railways of Harbin-Dalian,Changhun-Hunchun and Harbin-Qiqihar.The information flow shows"four cores,four edges"pattern
