【摘要】：统计铁路网络的拓扑特性,分析其与社会经济的关联关系,研究铁路网络演化原理和机制,为科学的规划铁路网络,合理的确定建设时序,有效的优化网络提供理论基础和决策依据,对铁路网络的发展和完善具有重要意义。构建我国不同时期铁路线路网络,利用Pajek软件统计网络拓扑特性,分析网络不断演化条件下网络特性的变化趋势。比较相同时期社会经济发展趋势,明确铁路线路网络演化与社会经济发展的联动关系。运用灰色关联理论,以人均收入、人均国内生产总值、第三产业就业人数等指标构成社会经济系统的指标序列,以网络平均度、平均距离、集聚系数等指标构成铁路线路网络的指标序列,计算关联度,分析耦合作用,绘制耦合曲线,确定铁路线路网络演化与社会经济发展之间存在较强耦合作用。基于铁路线路的网路演化与社会经济发展的耦合作用,以及线路网络与列流网络的内在联系,以区域铁路客运需求作为上层网络,以区域城际铁路列流网络作为下层网络,构建局域尺度的双层网络演化模型。设计节点增加和退出,边的连接,点权和边权的演化机制,以及上下两层网络的互馈影响机制,给出模型算法步骤。
[Abstract]:Statistics of the topological characteristics of railway network, analysis of the relationship between railway network and social economy, study of the evolution principle and mechanism of railway network, in order to scientifically plan the railway network, reasonably determine the construction timing, It is of great significance for the development and improvement of railway network to provide the theoretical basis and decision basis for the effective optimization of the network. In this paper, we construct railway network in different periods of our country, use Pajek software to calculate the network topology characteristics, and analyze the changing trend of network characteristics under the condition of continuous evolution of network, and compare the trend of social and economic development in the same period. The relationship between the evolution of railway line network and social and economic development is clear. Using grey correlation theory, the index sequence of social economic system is constituted by per capita income, per capita gross domestic product (GDP), employment population of tertiary industry and so on. The index such as agglomeration coefficient constitutes the index sequence of railway line network, calculates the correlation degree, analyzes the coupling action, draws the coupling curve, and determines that there is a strong coupling effect between the evolution of railway line network and the development of social economy. Based on the coupling effect between the evolution of railway line network and the development of social economy, as well as the internal relation between the line network and the network of current, the demand of regional railway passenger transport is taken as the upper network, and the network of regional inter-city railway as the lower layer network. The local scale two-layer network evolution model is constructed, the node addition and exit, the edge connection, the point weight and the edge weight evolution mechanism, and the mutual feed mechanism of the upper and lower layers network are designed, and the algorithm steps of the model are given.
