Region division is the foundation of regional socio-economic development planning. Traditional regional division is only built upon the information of attributes in each spatial unit. However, the spatial relationships and their spatial interaction between units are ignored. In the study, based on the spatial linkage theory, the principle and steps of spatial units fusion of clustering algorithm is proposed. According the spatial range of Chinese railway as a case, determine the spatial units and the linkage model was built based on the proximity and attribute characters, the experiments of regional division for Chinese railway are achieved. The experiment shows the results are highly accordant with the real situations and have proved the feasibility of the algorithm.
