Abstract:

Based on S.Beer's "spatial resolution taper",applied hierarchical system theory and combined with present research result of hierarchical system,the article tried to set up "the unit hierarchical taper of regional geographic system",a kind of regional geographic system model which is a scale-unit structure.The article analyzed the structural relationship and unit constitute of the taper.The research result showed that "the unit hierarchical taper of regional geographic system" is made up of the following units: the unit of geographic minimum structure,the unit of geographic basic function,the unit of geographic landscape,the unit of geographic landscape class and the unit of geographic landscape class combination.They represent the geographic research methodologies of "the partition of minimum spatial granularity","the analysis of a basic spatial process","the conjugate analysis of spatial processes","class partition" and "reciprocity among the classes" respectively and embody the geographic research thinking of "redutive analysis","process analysis","whole analysis","class partition" and "synthesis analysis" respectively.In addition,the article conducted an experiment of the research method on structure of the unit hierarchical structure of regional geographic system in a particular experimental district.

Key words: regional geographic system, the unit hierarchical taper of regional geographic system, geographic computation methodology
