| In recent years,the rapid development of transportation network and the wide application of new technologies such as high-speed railway have greatly promoted the circulation of various elements among cities and promoted the development of urban areas and metropolitan areas.Uneven but as a result of traffic network and the diversity of the means of transportation,traffic efficiency difference is bigger,the development of city economic zone has a different nature of the guide,geographic location or path distance cannot as the city distance measure,and use of time distance reflect the traffic efficiency,more accurate.This paper takes Shandong province as an example to analyze the influence of time distance on the organizational structure of urban area and urban economic zone,and puts forward some suggestions for adjusting the structure of the existing urban economic zone in Shandong province.This article takes Shandong province as the study area,the selection of 107 at the county level and above in Shandong province as the research node,the formed by road and rail synthetical traffic network system as a foundation for network,respectively,with the help of ArcGIS geographic information platform,12306 railway official website to get the network time distance data.Using the time distance data as the distance index of the two places,the shortest travel time model is selected to analyze the traffic network characteristics.In multidimensional space fitting method to time distance visual expression in two-dimensional space,analyzed the influence of the time distance of city node location,the analysis results show that time distance has obvious imbalance in shandong province,has obvious deviation effect to node location.The city attractive model,using the node time distance data and city population data,calculation of the core cities to the other nodes city attraction,selection of node city biggest attraction at the heart of the city center for the city to set up the urban economic zone,and the number of nodes in accordance with the urban economic zone of central city hierarchy,forming based on the distance of the city economic zone time structure.This paper analyzes the structure of the urban economic zone,and puts forward some suggestions for the development of urban circle and metro area in Shandong province.The city attractive model,using the node time distance data and city population data,calculation of the core cities to the other nodes city attraction,selection of node city biggest attraction at the heart of the city center for the city to set up the urban economic zone,and the number of nodes in accordance with the urban economic zone of central city hierarchy,forming based on the distance of the city economic zone time structure.This paper analyzes the structure of the urban economic zone,compares the current situation of the development of the urban economic zone in Shandong province,and puts forward some suggestions for the development of the urban circle and the metropolitan area in Shandong province.In this article,we will in time as the main impact of urban economic zone structure parameters,analyzes the shortest travel time,the space location fitting analysis,the urban economic zone structure analysis,the transportation network system construction and urban economic zone construction planning of Shandong province proposed the following suggestions:first,to strengthen the construction of the longitudinal and transverse rapid transport channel,the overall improving transportation efficiency and strengthen the local areas,especially the southern region of the fast-track and road network construction,compress the time distance with central region;Second,adjust Qingdao-Weifang metropolitan area and Linyi-Rizhao metropolitan area to Qingdao-Weifang-Rizhao metropolitan area and Linyi metropolitan area,giving full play to the advantages of the Rizhao area of coastal economic,.So,Weihai,Yantai,Qingdao,Rizhao can form coastal development belt;Thirdly,strengthening the role of Weifang in the second central role of Qingdao-Werfang metropolitan area,and promoting the connection between the mainland and coastal cities in Weifang city circle;As a link between Jinan city group and Dongying-Binzhou city group,strong Zibo city is driving the development of the urban cluster in Dongying-Binzhou city.To strengthen the city function of Zaozhuang city,and to form the economic group of Jining-Zaozhuang-Heze economy zone,and to promote the formation of development belt in southwest Shandong province.Forth,The county-level nodes that are not included in the urban economic zone shall be included in the corresponding urban areas according to the scope of urban attractions. |
