——些塾型Abstract ——些塾型 Abstract Spatial relations include those relations of topology,direction and distance and so on．Study on description models ofspatial relations mainly focuses on the relations oftopology and direction． The 9-intersection model for topology relation and direction·relation matrix model with good description capacity also have their own weakness．For example，the 9-intersection model which is used widely in some commercial software c∞t distinguish the instance oftouching at the point touching m the line for regions,or describe the neighborhood relation．The model is helpless for describing topology relation between objects and complexity region which has hollows．The widely used direction-relation matrix model is not good at describing the interior direction ofthe region object elaborately and can、describe direction of line object．The urban planning decisions consist ofcomplex data．From the point ofview ofdetailed extent，they include strategic planning decision and detailed planning decision．From the angle of special planning,the urban planning decisions consisted of land planning decision,roadway traffic planning decision， foundation facilities planning decision atc．From the angle of exhibition form，the decisions include decisions of texL forms，maps and pictures．The problems of especial spatial relations discussed above are widely existent in spatial data and text descdption ofurban planning decisions． The relations bebⅣeen these decisions are strong and should be described and recoguised Then the management and analyse of urban planning decisions will be easy．There is not enough study on these spatial relations in China and abroad．So the description models and the algorithms ofspatial relations are argued in this article． In this article，the studying evolution and application ofspatial relations and their description models am analyzed．The description methods of spatial measurement relations are argued．The basic theories are introduced and the descri
