China high-speed train service networks are built based on complex network theory. Indices of complex network were defined and explained for the presented networks, thus characteristics of the train service networks presented with Space L and Space P structures were studied and compared. Travel time and service frequency were considered for weights measurement and between calculation, which provides an access to quantitative evaluation of network influence of railway stations. Then, a local network considering transfer concept was built with Space P structure, and a modification method for network generation considering train connection relationship was proposed. Case study of Wuhan station proves the effectiveness of the modification method. Results show that according to current train service plan, each high speed station is connected with average 52.3 other stations by direct train services, and each pair of stations can be connected by average 1.1 transfers. Indices of accessibility, hub influence and service frequency do not match for some of the stations. The presented train service network generation method and conclusions of network characteristics have significance as reference for high-speed train service network performance evaluation and optimization.%基于复杂网络理论,构建我国高速铁路列车服务网络,阐述复杂网络的指标在列车服务网中的实际意义,对比分析Space L和Space P 2种网络构建方式下高铁列车服务网络的基本特征,并引入旅行时间和服务频率2种权重计算介数,实现对铁路车站枢纽影响力的量化评估.利用Space P方式构建考虑换乘服务理念的局部网络,针对列车接续关系及其特征,提出对接续关系的修正表达与网络构建方法.以武汉站为核心的局部网络为例,通过对比修正前后网络特征的变化,验证修正表达方法的有效性.研究结果显示表明:现行列车开行方案下,每个高速铁路车站平均与52.3个车站有列车直接通达,任意2个车站间平均通过1.1次换乘可以到达.部分车站的可达性、枢纽影响力、服务频率特征不匹配.论文提出的网络构建方法与特征分析结论对高铁列车服务网络性能的综合评价与优化调整具有参考意义.
