China is now in the stage of reconstruction and transformation of rural settlements. During this period, the social connections of farmers between villages have been widely used to assist rural relocation planning.. The structure of these connections may change under the impacts of future rural development policies. Neglecting this change will result in unrealistic relocation options and reduce the potential applicability of relocation plans in the future. Our study proposed a spatial relocation model that incorporated social connections between villages and their potential changes under different rural development polices. The model searched for the optimal relocation solutions with maximum inter-village connections and maximum spatial compactness of relocated settlements using an integrated approach of particle swarm optimization algorithm and geographical information system. Taking Liji Town in central China as a case study, we established a social network based on a questionnaire survey of farmer daily activities, and simulated the potential change of current networks under different rural development policies to examined how connection change influences relocation outcomes The results demonstrate the significance of integrating inter-village connections with rural relocation solutions. This study is capable of providing alternative relocation plans to reduce uncertain effects of policy interventions.
