摘要
在研究总量控制理论的基础上,运用GIS的最小生成树原理和节点重要度布局法对郑州市的节点体系的重要度进行了聚类和分级;在计算路段重要度和路线重要度基础上,生成了公路网重要度最大树,并对郑州市公路网的布局进行了分层和优化.
The paper has carried out clustering and classification of the system important degree of the Zhengzhou City and town systems. The highway network arrangement theories was discussed using the most superior spanning tree＇ s principle and the method of the pitch point importance. The author has generated the maximal tree of highway network important degree based on the important degree calculating section important degree and route. The author has also stratified and optimized the highway network layout of Zhengzhou.
