Abstract:

This paper constructs a special data structure model for montane altitudinal belts (MABs) and thereby realizes their digitalization and visualization. A three-level hierarchy is drawn for MABs classification: the first level is "spectra series" with the same base belt. A total of 31 basic spectra series can be generalized for China; the second level is "spectra group" with the same characteristic belts; the third level is "spectrum type" with the same structure of MABs. Seven models are identified for the spatial variation of MABs: (1) identical structure model; (2) structure-thinning model; (3) mutation model; (4) latitudinal descending model; (5) longitudinal thinning-rising model; (6) step-ascending model; and (7) superimposed model. Five ecological types of MABs are also distinguished as follows: (1) climax MABs related with regional climate; (2) standard MABs related with main mountains; (3) special/transitional MABs related with special geoecological phenomenon; (4) disturbed MABs related with human disturbances; and (5) secondary mabs related with intensive human activities. Digital comparison and analysis of mabs could reveal more geographical information than ever before.
