摘　　要：针对现有城市地铁网络结构评价研究的不足,该文提出运用中心性评价方法分析地铁网络中站点的重要程度,实现对网络结构的评价:引入中心性方法的度中心性、介中心性和邻近中心性指标,提出一种基于客观权重赋权法的系统中心性评价指标,对地铁网络的中心性进行计算。以广州市为研究区域,分析了广州市地铁网络中心性空间分布和频率分布特征。结果表明,较现有线网,广州市地铁规划线网各项中心性指标分布更为均匀,市辖区间联系更为紧密。中心性评价指标能够对非采用单一票制的广州地铁系统的网络结构进行评价,为规划方案的制定提供参考。Aiming at the insufficiency of current evaluation study on urban subway network structure, the paper used centrality evaluation to analyze the importance of the stations in metro network for achie- ving the evaluation of metro network structure： three different measures of centrality, namely degree, closeness, betweenness were calculated for presenting a comprehensive evaluation index of system central- ity based on CRITIC method. Taking Guangzhou City as the study area, it calculated the network centrali- ty of subway system in Guangzhou by analyzing the spatial distribution and frequency distribution of the metro network centrality. Result showed that compared with the existed metro network, centrality indexes of planning network were well distributed and municipal districts were closely connected. Therefore, cen- trality index could be applied to evaluate the Guangzhou subway system that does not use flat fare and pro- vide a reference for the planning.
