Based On The Intensity Of Contact Ha-Chang Urban Agglomerations Pattern Of Urban Network

Economic development of globalization, information of network coverage, traffic convenient way into the connection between the city provides the foundation and motivation, the dynamic and real-time, implements the flat and accessible. Traditional hierarchy and size distribution of theoretical thinking and research methods can not fully understand the present problems of communication between cities, urban areas of the coordination and division of labor, complementary relationship between urban network study become a part of the national and regional strategy development. Therefore, the city network of research increasingly important.Based on Ha-Chang urban agglomeration as the research area, this paper selected user attention in 2013, 2015, baidu index data and 2016 inter-city passenger transport flight, and population, economy and other data, using baidu index, relative efficiency index, the index of absolute efficiency, as well as the combination of quantitative and qualitative analysis system, using ArcGIS software intuitive to express urban network space structure, double from baidu index and intercity passenger traffic flow analysis Ha-Chang urban agglomeration in the perspective of network characteristics. Comprehensive analysis using the linear regression model of urban network structure influence factor. Finally, from the optimization of space development pattern, strengthening the construction of connectivity, promote the development of economic complementarity, break administrative barriers restrict, train high quality practical talents, improve the overall level of the urbanization on Ha-Chang urban agglomeration in network optimization countermeasures and Suggestions. The results show that:1. Ha-Chang urban network in changing, the rapid development stage. Harbin, changchun is the core of urban network, urban network hierarchy, structure stability as a whole. Harbin is radial urban core backbone network and are connected to the jilin, is still the "Angle" type "Angle" of urban backbone network.2. Harbin, changchun is the urban agglomeration in the black, long ji provinces domain information flow intensity center in 2013. Harbin, daqing, qiqihar, mudanjiang, that is suihua in heilongjiang province; Changchun, jilin province, jilin, matsubara city link between more closely. Relative efficiency index of population from 2013, Harbin, daqing and qiqihar, mudanjiang, that is suihua city and for Harbin, daqing and qiqihar, mudanjiang, For mudanjiang, that is suihua daqing; In changchun, jilin, siping, matsubara, in terms of yanbian long-withering; In changchun, jilin siping, matsubara, yanbian, long-withering: For changchun, jilin, siping matsubara, urban awareness higher per ten thousand people, with a larger amount of information, the city more development potential and the flow of information. Daqing, mudanjiang, long-withering per capita information more liquid. Relative efficiency index, GDP from 2013 to Harbin, daqing and qiqihar, mudanjiang, that is suihua in qiqihar, mudanjiang, that is suihua; For Harbin, that is suihua, mudanjiang, daqing qiqihar. In changchun, jilin, siping, matsubara, in terms of yanbian long-withering; For yanbian mudanjiang. For matsubara, long-withering jilin; In changchun, jilin, matsubara, yanbian, in terms of long-withering siping; For changchun, siping matsubara; For, siping, jilin yanbian, these cities each information more, produced by one hundred million yuan per unit of economic output of the information flow is larger, the flow of information have a positive impact on economic development of city. From 2013 years absolute efficiency index of population, the trunk network(except that is qiqihar, suihua) every one million people in the city produce large amount of information, strong attractive to other cities; Long-withering internal vitality, attraction more apparent. From 2013 years absolute GDP efficiency index, qiqihar, mudanjiang, Harbin unit of economic output generated by information flow is larger, larger contribution to the information flow, that is suihua, siping, jilin, changchun, matsubara, yanbian, long-withering relatively moderate, daqing at least.3. Ha-Chang spatial differentiation characteristics of urban network connection strength, the direction of the contact space organization characteristics, the spatial structure features of contact nodes. Movements of contact strength and "HaDaQi Mu", "ChangJiTu" two main economic development belt and Ha-Chang urban agglomeration development. Harbin, changchun is a network connection strength’s biggest city, network connection and influence the whole city. Local center city more obvious influence on surrounding satellite cities. Contact direction clearly aimed at city of Harbin, changchun network core cities, agglomeration effect; County-level cities, there is no significant cross-border links, local area each county contact direction pointing to the center city is more obvious and universal. Contact nodes show the hierarchical structure features of dual core-edge distribution and structure properties of differentiation.4. In this study, GDP, the number of broadband Internet users, the ordinary university students, the mobile phone users in urban network connection strength to some extent, the influence of the impact on urban network structure; Urban population, the third industry in GDP proportion of GDP, have certain influence to highway mileage of urban network connection strength; Accounts for the second industry produce gross area GDP, traffic density, the proportion of non-agricultural population of urban network pattern of ha long urban agglomeration effect research still has the effects of analysis.
