    Abstract:

    Representation of the uncertain spatial information of the vague regions and handling the vague regionrelations are focus of research on the spatial database, geographical information systems and computer vision etc.To deal with the indeterminate membership of the vague points and the complex dynamic vague region relations,the static and dynamic vague region relations are discussed systematically based on vague sets. The vague region’sdefinition is formalized and the vague region partition for the vague region with or without kernel is also givenbased on the vague sets. The three basic vague region relations are studied and the dynamic basic vague regionrelations are also presented. The relation table for the vague regions with kernel and the implicative relations of the vague sub-regions are given. The dynamic vague region relations of the vague regions with kernel are studiedsystemically and the dynamic adjacent relation table is also given in detail. Furthermore, the analysis of an instanceis made. The production in this paper can deal with the indeterminate membership information of the vague pointsin vague regions, the dynamic vague region relations and forecast the next dynamic relations.
