Les auteurs proposent ici une organisation du traitement des données en phytosociologie et phyto-écologie. L'organisation repose sur un système bien développé pour rassembler et codifier l'information des reléves. (fig.1). Un ordinogramme (Fig. 2–5) présente l'agencement et l'enchaînement des différentes méthodes d'analyse des données (profils écologiques,(More)
