New similarity indices for the assignment of relevés to vegetation units of an existing phytosociological classification
Original language description
Every proposed vegetation classification is sooner or later confronted with an accumulation of new data, which has to be assigned to existing vegetation units. Indices similarity between new relevés (vegetation plots) and constancy columns of vegetationunits is a suitable for assigning the relevés to these units. This paper compares several similarity indices using simulated data sets of which the relevés include in the species composition either randomly distributed or diagnostic species. Traditionalindices, based only on species composition, and similarity indices, which include species fidelity, differ. However, both types of indices failed in some situations and thus are not reliable methods of additional relevé assignment. Therefore a combined Frequency-Positive Fidelity Index is proposed. This new index includes compositional similarity and retains the advantages and lacks the disadvantages of tested indices. Procedures for calculating of all these indices are available in the

Nové indexy podobnosti pro přiřazení snímků k vegetačním jednotkám existující fytocenologické klasifikace
Czech description
Článek popisuje možnosti dodatečného přičlenění fytocenologických snímků k vytvořeným vegetačním typům. Srovnává použití indexů podobnosti fytocenologických snímků založených na frekvenci a fidelitě a analyzuje jejich přednosti a nedostatky. Nakonec navrhuje nový index, který kombinuje frekvenci a fidelitu, a nejlépe tak odráží fytocenologickou příslušnost snímků k určitému typu vegetace.
