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。
The social-spatial linkages at the village level reflect the real needs of rural settlement production and living. This paper presents an improved gravity model based on rural comprehensive quality measure. Taking Liji Town in Huangpi District of Wuhan as an example, this paper constructs a simulation network of rural social space and verifies its suitability at the village level. At the same time, with the help of field survey data, Social network analysis method to build Li Jizhen actual space network, to evaluate the overall network characteristics and core - edge, cohesion subgroups and other structural features. The results show that: 1) The simulation network constructed based on the improved gravity model can not explain the spatial relationship between village and village well. Simulation network has the effect of narrowing the development gap between village and village in real life. 2 The simulation network has strong dependence on the road, the nodes in the network are driven by roads, and the nodes in the physical network are mainly driven by the socio-economic activities. 3 The rural social space of Li Jizhen has a small contact network density and a low overall network density. The core edge structure shows the contact pattern of “high in the middle part, low in the west part and lack of the east part in the east part.” The whole town contains 4 cohesive subgroups, Sub-group internal relations are not strong, the relationship between sub-groups is weaker, “very core village ” has a greater impact on the connection between sub-groups. The results of the study better reflect the network characteristics of village-level social spatial relations and provide decision-making support for the construction and planning of villages and towns.
