摘要： 分析了辽宁省公路交通网络的基本现状，根据分形理论，利用Hausdorff维数简化算法和空间关联维数的计算方法，测算了以省内国道干线为基础的辽宁省公路交通网络的分维数和网络直通度.通过对比分析数值得出辽宁省干线公路网络的分维数比较低，网络直通度比较高的结论.并指出辽宁省公路交通网络应从提高网络直通度向提升线路等级，从而向缩短运输时间、增大运量的方向转移.

Abstract: This paper analyzes the basic status quo of Liaoning’s highway network，Based on the methods of Hausdorff fractal dimension and space relation fractal dimension, the paper advances calculation models on the fractal dimension and the arriving degree of network of Liaoning’s highway network. The results have deminstrate that the Hausdorff fractal dimension is comparatively low and the space relation fractal dimension is high according to the ratio. The conclusions point out that Liaoning’s highway network should shift its focus from increasing its arriving degree to improving its line grade so as to decrease its transport time and increase transport volume.
