摘　　要：利用P空间模型组织焦作城市公交网络,结合复杂网络科学,分别以乡镇(街道)和公里网格为基本空间单元,分析网络特征,对节点进行聚类和耦合协调性分析。结果显示:焦作公交系统存在线路分布不合理、站点分布密度不均、服务盲区等问题;焦作公交网络节点的中心集聚性较强,节点的聚集与主要功能相关,主要功能为教育、娱乐的节点与周围节点的聚集性更强;焦作公交网络服务与实际需求的协调性不理想,多数节点处于弱协调和轻度失调状态。本文最终得出焦作公交网络与城市居民出行需求匹配不一致的结论,可为焦作公交系统规划提供科学参照。The P-space model,combined with complex network science,is used to design Jiaozuo urban public transport network,with towns and kilometer grids as basic spatial units.The network characteristics are examined,and the clustering and coupling coordination of the nodes are analyzed.The results show that:Jiaozuo public transport system has problems such as unreasonable line distribution,uneven station distribution density,and service-blind spots;Jiaozuo public transport network nodes have strong central agglomeration,driven by the main functions of the nodes.The nodes whose main functions are education and entertainment have stronger agglomeration with the surrounding nodes;the coordination between Jiaozuo public transport network services and actual demand is not ideal,and most nodes are in a state of weak coordination and slight imbalance.It is concluded that the matching between Jiaozuo public transport network and urban residents’ travel demand is inconsistent.The research results can provide some scientific reference and suggestions for Jiaozuo public transport system planning.
