河南省城市交通网络的分形特征

The Fractal Features of the Transport Network of Henan Province

本文运用分形几何学方法考察了河南省城市—交通网络的空间结构特征，提出了空间关联维数等概念，建议使用牛鸦维数比和网络维数等指数反映区域交通网络的复杂度、通达性和空间分布形态，文章应用上述分维及有关指数、借助系统数据分析了河南省城市—交通网络的现状及其存在的问题，指出了优化的方向。

A preliminary study was made in the paper on the network of communication lines based on the systems of cities and towns in Henan Province. The concept of spatial interrelation dimension was presented and calculated,and two new indexes,cow-crow dimension ratio and network dimension were suggested to describe or characterize transport networks in a region. The fractal features of Henan's transport networks was brought to light and the direction was indicated to improve the communication systems with geo-fractal theory and related technique.
