Accessibility Research Based On Social Network Analysis Of Chongqing Main City Park Green

The traditional urban park green evaluation index focuses on the rationality of the layout of green space construction and quantity to measure, such as urban park green rate, per capita green area index, and urban parks should be scientific and rational layout planning is to consider many factors, including the public convenience to the city park is one of the important the index of urban transit system as the main part of the construction of transportation infrastructure in the city, on whether it can meet the configuration requirements of urban parks is necessary, to the layout of the traffic planning guidance, connectivity, improve the public transport system in urban parks, urban parks meet between bus lines up to the objective. Park green space exists between the social attribute is outside the scope of existing green space accessibility of multi with GIS as technical support, focus in study of park green space itself up to level, to urban road as the research starting point, the main analysis of the residents living area and the park green space of urban road travel time, this study for the consideration of drag considerations and resident trip transportation is a kind of intuitive judgment, and the lack of transport network reachability analysis. Therefore, this thesis attempts to use sociology method on the park green space accessibility of research and analysis, social network analysis method to analysis the relationship between mainly, different in traditional on the parks attraction considerations, to each district all park green space as the research object, examine whether there is public transportation accessibility between pairwise, for residents in the region choice garden provide a travel reference. Is also the research way one kind of innovation, and the subject fusion.This paper intends to build a system of parks and city bus lines through social network analysis, "the overall planning of urban and rural areas of Chongqing city(2007-2020)" reached the national standard for the green area of the park, made a new plan for the park, selected in the delineation of the main urban area of Chongqing City 312 park green block as the research object, their number to two, the two mutually between bus lines will be reached as basis, construct the network model of the nine district bus up through Ucinet 6 software platform, and use the method of social network analysis and quantitative analysis of network data, reasonable allocation of bus lines comparing each district in the Green Park, in order to guide the future traffic planning.The first part of this paper is a literature review. First of all to the city park green space, green space system in urban areas of Chongqing, social network and social network analysis method and reachability defined the concept and to determine the object of study and analysis of the typical, again from the urban green space system, social network analysis method and up to three aspects of research, respectively, to explore their research progress at home and abroad, and previous studies that the applicability.The second part is the research on the current situation of the city park green space construction in Chongqing city. Under the background of world city park green space construction, by Chongqing city park green space construction in the historical process of elaboration, Chongqing city park green space in the development of internal and external evolution, finally get the problems occurred in the construction, through the analysis to find the influence of reachability problem in the construction of park green space in Chongqing, put forward to solve reachability problems, to provide the basic research.The third part is the semantic and network model of public transportation network in the park of Chongqing city park.Through expounding the necessity of study on the road traffic in the green land accessibility and the important role of urban infrastructure, public transportation accessibility and not as a "line" in the construction of network, park green space as "points" build nine zone network model.The fourth part is to construct the network model of the nine part of the city, and then analyze the attribute of the network itself. Calculate the attribute index, network density, cohesion coefficient, Lambda collection, center, etc..The fifth part is the summary of the full text.Analyze the network attribute index of nine areas, get the overall health evaluation of the network, and comb the framework of the paper, and propose the innovation and limitations of the paper.
