【摘要】 随着城乡一体化的推进,城镇结构优化成为区域研究的重要议题。对于城市间联系度的分析及动态研究是理解区域城镇结构的重要切入点。基于流空间视角,借助经济统计数据、公共交通出行数据、互联网信息检索数据等多源数据,通过对联系度评价方法进行创新,以引力模型测度经济联系度、以动态铁路、长途汽车客运数据测度交通联系度、以百度城市搜索指数体现信息流测度信息联系度,最后将三者进行耦合得到湖北省17个地级市间联系度的综合评判,并基于凝聚子群分析法对其形成的城市集群进行划定。结果表明:(1)湖北省西北部地区交通与经济联系不协调,尤其是铁路(客运)交通难以匹配与其他地区的经济联系;(2)信息流方面,中心城市武汉表现出强大的外向信息流,而次级城市间的信息流则表现为均质的网络结构,整个地区形成围绕核心城市的二级圈层结构;(3)城市集群划分方面,武汉城市群体现出良好的协同发展态势,宜昌、荆州、荆门逐步形成协调的城镇组织,而围绕襄阳为核心的北部地区则尚未形成足够的集群规模。当前正处于城镇化结构转型重要时期,对区域一体化研究方法探索及地方城镇结构优化的研究具有重要意义。更多还原

【Abstract】 With the advancement of urban-rural integration,optimization of urban structure has become an important issue in regional research.The analysis and dynamic study of inter-city linkages is an important starting point for understanding regional urban structure.Based on the flow space theory,with the help of economic statistics,public transport travel data,Internet information retrieval data and other sources of data,this article innovates the evaluation method of connection degree,measures economic flow with gravity model,reflects traffic flow with dynamic railway and long-distance bus passenger transport data,and reflects information flow with Baidu City Search Index,and obtains 17 prefecture-level cities in Hubei Province.Comprehensive evaluation of inter-connection degree and delimitation of urban clusters formed by it.The results show that:(1) the traffic and economic links in the northwest of Hubei Province are not coordinated,especially the railway(passenger transport)traffic is difficult to match the economic links with other areas;(2)In terms of information flow,Wuhan City,the central city,shows a strong outward information flow,while the information flow between secondary cities shows a homogeneous network structure,and the whole region forms a secondary circle structure around the core city;(3)As for the division of urban clusters,Wuhan urban agglomeration shows a good cooperative development trend.Yichang City,Jingzhou City and Jingmen City gradually form a coordinated urban organization,while the northern area centered around Xiangyang has not yet formed a sufficient cluster scale.At present,it is in an important period of urbanization structural transformation,which is of great significance to the exploration of regional integration research methods and the optimization of local urban structure.更多还原
