The mathematic model representation of Jrv rough Vague region relation was given based on Vague set and rough set in order to deal with the important Jrv rough Vague region relation. The dynamic relevance adjacency graph of rough Vague region relation was determined through analyzing the complex rough-transform situation of the rough Vague region relation. The possible implication expression table was proposed based on the upper approximation and lower approximation of the rough Vague region. The possible implication expression of the Jrv rough Vague region relation was given. The analysis of an instance was discussed. Results show that the model can greatly enhance the ability of the spatial database for the complex uncertain region relation．
