Abstract: In the Han Dynasty, LuJiang prefecture belonged to Yangzhou, and had superior military strategic value.But because its location was relatively far away from the political center, the position of Lujiang prefecture was not outstanding in the whole political system during the Western Han Dynasty. Since the end of the Western Han Dynasty, with the change of social political situation, the military function of Lujiang prefecture began to be gradually highlighted. The selection and political activities of the prefects, the highest administrator of Lujiang prefecture, also showed different characteristics in different social periods. This paper probes into the close
relationship between the selection, relocation and political activities of the prefects, and the whole social political situation through the investigation of the prefects of Lujiang prefecture in Han Dynasty, which enriches the study of the history of bureaucracy and politics in Han Dynasty.
