Abstract

Various possibilities of usingSörensen’s coefficient of floristic similarity in plant sociology are summarized. A new formula (11). derived from that bySörensen and based on constancy values, is suggested in order to calculate the mean floristic similarity within a set of relevés.

Zusammenfassung

Der vorliegende Artikel fasst alle Möglichkeiten der Anwendung desSörensen’s Koefizienten der floristischen Verwandschaft zusammen. Die im Text angeführten Formeln dienen zur Berechnung der durchschnittlichen floristischen Verwandschaft zwischen zwei Gruppen der Aufnahmen und zwischen der Gruppe und der selbständigen Aufnahme. Zwei Formeln (11) und (12) werden neu vorgeschlagen, die zur Berechnung der durchschnittlichen floristischen Verwandschaft in den Grenzen einer Gruppe der Aufnahme dienen, wenn nur Konstanzwerte verwendet werden.
