摘　　要：村层次的社会空间联系反映了农村聚落生产生活的现实需求。文章提出了一种基于农村综合质量测度的改进重力模型,以武汉市黄陂区李集镇为例,构建农村社会空间联系模拟网络,并验证其在村层次的适用性;同时借助实地调研数据,运用社会网络分析方法,构建李集镇实际空间联系网络,评价网络总体特征及核心—边缘、凝聚子群等结构特征。结果表明:1基于改进重力模型构建的模拟网络并不能很好地解释村与村之间的空间联系,模拟网有缩小现实生活中村与村之间发展差距的效果。2模拟网络对道路的依赖性强,网络中节点联系以道路驱动为主,而实体网络中节点联系以社会经济活动驱动为主。3李集镇农村社会空间联系网络密度较小,网络整体紧密度较低,核心边缘结构表现出"中部高,西部低,东部缺联"的联系格局;整个镇包含4个凝聚子群,子群内部联系不强,子群之间联系更弱,"极核心村"对子群之间的联系影响较大。研究结果较好地反映了村层次社会空间联系的网络特征,能够为村镇建设和规划提供决策支持。Social Spatial interactions on village reflect the current needs in producing and living conditions of rural settlement. Based on comprehensive quality evaluation of improved gravity model, the authors try to construct spatial interaction simulative network in rural society in Liji Town, and verify the applicability of the simulative network on village level. With the method of social network analysis and investigating data, the authors are going to assess the general features and structural features like the core- periphery and subgroups of the real network in Liji town. The results indicate that（1） the simulative network based on improved gravity model cannot well explain the spatial interaction between villages, because of narrowing the developing gap between villages in real life.（2） Simulative network heavily relies on roads, and the nodes connection gives priority to roads, while nodes connection is mainly on social and economic activities in real network.（3） The density of spatial interaction in rural society is small in Liji town,and the compactness of network is low. The core-periphery structure shows the combination layout which is high in the central, low in east and west areas. The 4 subgroups in Liji town have a weak combination between each other, while the inner- interaction in a subgroup is not significant either, and the core villages greatly affect the interaction between subgroups. The research nicely reflects the network characteristics of spatial interaction in society on town-level, and can be supportive to the rural planning and construction for government.
