Geographic location which can generally be described either absolutely or relatively is the locating information of a spatial object in geographic environment. Absolute method takes use of words or numbers that uniquely identifies the location of spatial entities, such as latitude and longitude coordinates, address, etc. by establishing a unified coding system. On the contrary, relative method locates a target object by the spatial relation between the target and its reference, which is coincident with people's spatial recognition habit and follows the development trend of socialization GIS service through combination with natural language. However, single sentence describing target location can cause such deficiencies as reliance on the very reference object and large uncertain locating area. This paper proposed a combinative description method to combine single description sentences of different reference objects and different spatial relations into one paragraph to approach the target location and diminish the reliance on the single reference object. Reference objects were cataloged to different types according to their characteristics: distinctive geographic semantics, a particular structure, and spatial relation constraints with the target object. Means of choosing various reference objects were discussed, and parameters of location information according to various reference objects such as spatial relations (including topological relation, direction relation and distance relation) as well as polylines' strike and polygons' extent were listed out, computed and transformed into corresponding words which were then filled into a sentence within the syntactic pattern. Under the principle of combination, single sentences were grouped into a comprehensive paragraph. The description experiment comparing single description sentence and combination paragraph showed that this approach attained various spatial recognition level and locating structure, and was preferable to better understand and locate a geographic location.
