We also treated the methodology for the classification of several spatial units o community and vegetation complexes, which are principal constituent elements of a landscape. A sigmataxon (sigmetum) is recognized as a spatial unit of community complex occurring in a series of vegetational succession on a tessela characterized by unique vegetational potentiality. A geosigmataxon (geosigmetum) is a complex of several tesselas, each having different vegetation vegetational potentiality. The geosigmataxon occurs on a catena as a unit of land system, in which each complex of tesselas conjoining with mosaici or zonal patterns repeats itself with a catenal pattern. The sigmataxon and geosigmataxon, with their respective arrangements by serial and catenal criteria, have proven effective for mapping large- or medium-scale vegetation landscapes for ecological analysis evaluation. On the other hand, the so-called community group, which a unit of community complex derived from a unit system of vegetation geography, is also reliable concept for use with vegetation landscapes showing mapped on a small or medium scale.}, pages = {127--137}, title = {景観生態学の基盤としての群植物社会学の理論と方法論}, volume = {23}, year = {1997} }
