Nouvelles recherches sur les structures systématiques végétales: Caractérisation, ordination, signification
De Foucault, B.
With the usual phytosociological methods, the author points out several "systematic structures", syntaxa defined on the basis of an original combination of vegetal families, not of vegetal species. Determinism, chorology and an hierarchical ordination of these structures are presented. Finally, the author analyses the significance of this study, bringing together systematic hierarchy and physic measure units.
