摘　　要：黄河流域城市协调发展是实现区域高质量发展的关键。以黄河流域90个市(州、盟)为研究区,通过修正引力模型,测度城市间的联系强度,借助社会网络分析法从流域尺度剖析城市空间联系“点—线—群”的网络结构特征。结果表明:①黄河流域城市空间联系网络密度较低,越往下游联系网络越密集,全流域的联动效应不足;中上游城市联系网络的关联度较低,网络可达性较差。②省会城市点入度高于点出度,在网络中城市吸引力强于辐射力;兰州、西安、郑州分别为上、中、下游联系网络的控制核心;银川、西安、郑州分别能在上、中、下游城市联系中迅速与其他城市产生联系,在城市联系的要素传递上较便捷。③一级网络关联线以郑州、西安、济南为核心,吸引或辐射邻近城市;二级网络关联线形成以郑州、济南、青岛、太原四大都市圈为核心的联系网络;三级网络关联线初步构建起全流域的联系网络框架;四级网络关联线形成了核心—边缘式的全流域城市联系网络格局。④黄河流域城市空间联系网络中4个板块内部存在显著的“俱乐部”集聚效应,但板块间的关联关系未构建起完整的要素传递路径。The coordinated development of cities in the Yellow River Basin is the key to realize regional high-quality development. Taking 90 cities(prefectures and leagues) in the Yellow River Basin as the research area, this paper measures the connection strength between cities by the modified gravity model, and analyzes the "node-relational tienetwork cluster" network structure characteristics of urban spatial connection with the help of social network analysis method. The results show that: 1) The density of urban spatial connection network in the Yellow River Basin is low,the more downstream,the denser the network,the linkage effect of the whole basin is insufficient. The connection degree of the urban network in the middle and upper reaches is low,and the network accessibility is weak. 2) The in-degree of node is higher than the out-degree of node in capital cities, the urban attraction is stronger than the radiation force in the network. Lanzhou,Xi’an and Zhengzhou are the control cores of the upstream,middle and downstream contact networks respectively. Yinchuan, Xi’an and Zhengzhou can quickly connect with other cities in the upstream, middle and downstream urban connection respectively,which is more convenient in the transmission of urban connection elements. 3)Zhengzhou, Xi’an and Jinan which are the core of the first-level network connection lines can attract or radiate neighboring cities. It takes Zhengzhou, Jinan, Qingdao and Taiyuan as the cores of the second-level network connection lines. The three-level network connection lines initially establish a basin-wide connection network framework. The fourlevel network connection lines form a core-periphery pattern of urban spatial linkage network in the whole basin. 4) In the urban spatial connection network of the Yellow River Basin,there is a significant "club" agglomeration effect within the four plates,but the correlation between plates does not construct a complete factor transmission path.
