摘　　要：探究城镇网络特征是城镇体系研究的重要内容。既有研究较少关注中观区县尺度且缺乏不同类型的网络对比。文章以天津市武清区为例,分别构建表征联系可能的空间本底网络、反映实际联系的人流通勤网络,从点、线、网3个层面对比分析二者特征。研究发现:①杨村街道在两种网络中均处于核心地位,边缘节点的人流通勤联系强度要弱于空间本底网络;②空间本底网络的点对联系格局为单核放射状而人流通勤网络为双核放射状;③两种网络的子群分布差异较大,整体网络完善度较低。建议从完善整体网络、增强局部联系、提升个体实力3方面进行优化。The study of urban network characteristics is an integral component of urban systems research.Existing studies often overlook the meso-district county scale and lack comparisons between different types of networks.Using Tianjin's Wuqing district as a case study,this paper builds a spatial background network for potential connections and a people flow network for actual connections,and compares and analyzes their characteristics across three levels:point,line,and network.The results indicate that Yangcun sub-district emerges as a core node in both networks,but edge nodes show weaker connection strength in the people flow network compared to the spatial background network.The spatial background network exhibits a singlecore radial point-to-point connection pattern,while the people flow network shows a dual-core radial pattern.Furthermore,there are significant differences in the subgroup distributions between the two networks,and both networks lack overall completeness.The paper suggests optimization in three areas:improving network completeness,enhancing local connections,and boosting individual node strength.
