%X As a radical method in geographical research, geographical regionalization has been widely used by geographers in their works, even since earlier times. But there are few documents devoted to the discussion of the geographical regionalization itself. The present article tries to probe into its connotation and contents of the geographical regionalization in the context of a methodology. As is well known, there exist similarities and dissimilarities among the geographical zones, and zonality is a universal theorem governing geographical distribution. Therefore, geographical regionalization exists objectively, and geographers just try to develop and construct an image of geographical realities. At the level of concept, geographical regionalization can be referred to a draft of regional division which meets some practical purposes, or a process a dividing region which adopts certain indexes and uses some techniques to divide an area (region) into many inter-related sub-areas (sub-regions), or a method to reveal the laws hidden in various geographical phenomena. As a draft, map-based form is a good way to describe the distribution of geographical features and phenomena. Clustering and classification are usually used in the process of regionalization in traditional physical regionalization. But these methods have little consideration of temporal variation of the geographical features. On the basis of analysis of the various regionalization drafts and plans, we proposed a scheme composed of five elements for geographical regionalization. Any regionalization must start from the understanding of the regionalization ontology composed of objects and aims and tasks of a geographical regionalization. The principles and criteria are the bases for the geographical regionalization and should be carefully designed and selected to fully meet the needs of the regionalization. Regionalization models include the model for dividing an area and determining the boundaries among the sub-areas. Regionalization information system stores the attributes of all sub-areas and provides the functions for assessing and simulating the draft of a geographical regionalization.
