Two phases of an urban agglomeration, landscape and function, have made it possible to make both landscape studies and functional studies. Both of them are considered, fundamentally from the same point of view; that is, to comprehend cities and their related phenomena from spatial or areal aspects. The writer would support the latter viewpoint functional approaches so far as a grave view of the principles and theories should be taken concerning some spatial order, structure, and mechanism that would be recognized within the spatial or areal spread of phenomena, but not a mere description, classification, or explanation of circumstances of facts.
Some concepts concerning the urban function have been devised, which are helpful for an understanding of the mechanism of both a network of urban centers and each of those centers. It is possible now to grasp an urban region as the spatial spread of urban functions as a whole. In addition, social physics has recently progressed all the more. Those are contributory to the additional elaboration of central place concepts. An integration of two notions of both functional and homogeneous regions has been tried by A.K. Philbrick to connect successfully urban geography with regional conception in general. The metropolitanization schema or a systematized principles of metropolitan areas, is being established as compared with central place schema on the one hand; on the other hand, even a corroborative comparison between the two schemata has been already tried, and an example was given by B.J.L. Berry. It should not be long before an integrated schema for both central place schema and metropolitanization schema should be proposed, which might be called an urbanization schema.
