摘要本文以徐州市交通网络道路为研究对象，利用ArcGIS软件的网络分析，空间分析等技术，对徐州市交通网络密度、交通网络服务范围、时间可达性、距离可达性及可达性系数等方面进行运算分析。计算分析出徐州市的交通可达性空间分布格局。分析表明：（1）徐州市区及其周边地区的交通网络密度最大并且高于全市的平均水平，丰县地区的交通网络密度最小。（2）徐州市交通网络服务分析，以徐州市各市县的行政区划中心为中心，在20分钟的出行时间范围内，徐州市区的交通通行范围比例最大为62。9%，丰县、沛县的较小分别为23。9%、32。67%。在0-30分钟的时间范围内可达性状况良好和可达性状况一般的占到60。7%，交通可达性整体上还是比较良好的。（3）通过计算分析徐州市内各区节点的交通距离可达性和时间可达性，可得出，随着距离徐州市区距离的增大，区内各节点的交通时间可达性和距离可达性也增大，并且时间可达性和距离可达性的分布模式都是呈现出以徐州市中心为圆心的向外递减辐射的同心圆模式，徐州市的整体可达性水平高于区内各节点水平，丰县、沛县、睢宁的可达性水平较低。76915

Abstract This article is using the Xuzhou city road traffic network as the research object, based on the network and spatial analysis techniques from ArcGIS software to analyze the density of Xuzhou city traffic network , traffic network service scope, time and distance of accessibility coefficient calculation analysis。 The result of the calculation analyzes the spatial distribution pattern of Xuzhou city’s traffic accessibility 。 Analysis showed that: (1) the Xuzhou city and its surrounding areas of the transport network density and higher than the city's largest average, minimum Fengxian region's transport network density。 (2) the Xuzhou city traffic network analysis in Xuzhou city administrative center of each cities and counties within the scope of the travel time of 20 minutes, the traffic range up to 62。9% of Xuzhou area, Fengxian county, Peixian county small were 23。9%, 32。67% respectively。 Within the scope of 0 to 30 minutes of accessibility in good condition and accessibility generally accounted for 60。7%, traffic accessibility overall is good。 (3) through calculation and analysis of Xuzhou city districts of the node traffic accessibility, accessibility and time can be concluded that with the increase of distance of Xuzhou city distance, accessibility of each node in the area of transport time and distance accessibility also increases, the accessibility of accessibility and distance and time distribution patterns are present in Xuzhou city center for diminishing the center outward radiation mode of concentric circles, the accessibility level of Xuzhou city is higher than the level of each node in the area of venture, Peixian county, Suining accessibility level is low。
