摘　　要：以整个东北地区(不包含蒙东地区)为研究区域,利用分形理论的半径维数和分枝维数测算方法以及地理网络空间分析来测度东北地区铁路交通网络的密度变化与复杂性量度的特征,具体包括了网络密度、连结度,以及各个城市的铁路网络通达度等.并以此来分析东北地区铁路交通网络的分布情况.对城市进行分类对比分析.研究显示在研究区范围内拟合较高,表明分形理论适用于东北地区铁路交通网络.通过对东北地区铁路交通的分形研究得出该区域内铁路交通的分布与个别城市职能存在差异性和不合理性.As the study area of the whole northeast area（ except East Mongolia）,analysis of the characteristics of density change to measure the Northeast Railway Traffic Network and the complexity measure using radius dimension and branch dimension calculation method of fractal theory and geographical network space,including network density,connectivity,and each city railway network accessibility,and the distribution of railway network in Northeast china are analyzed. Classify and contrast the cities. The research shows that the goodness of fit shows that the goodness of fit is higher in the whole calculation area,and there is no obvious spatial difference between the two regions. It shows that the fractal theory is applicable to the railway network in Northeast China. Through the fractal study of railway transportation in Northeast China,it is concluded that there is difference and irrationality between the distribution of railway traffic and the function of individual cities in this area.
