Spatial relation model is important technique f o r iniage indexing arid retrieval in iniage or niultiniedia databases. 2 -0 strings and its variants are proposed to s~rpport the representation of spatial relationship. In this paper, a new spatial knowledge representarion model rianied "Tvi.0 Diniension Begin-End boundan string"(2D BE-string) is proposed. The 2 0 BE-string represents on icon by its MBR boundaries. By applying a nuniber of "duniniy objects", the 2 0 BE-string can intuitively
