Evklidsko primerjanje sestojev po rastlinskih vrstah

Cedilnik, Anton (author), Robič, Dušan (author)

V članku je opisana metoda primerjanja sestojev glede na pojavnost rastlinskih vrst. V nasprotju z metodami, ki so ali so bile že v uporabi, je naše primerjanje čisto evklidsko: sestoji so enakovredni vektorji v mnogorazsežnem evklidskem prostoru (bazne smeri so rastline) in primerjave med njimi se izražajo z njihovimi skalarnimi produkti. Glede na rastlinske vrste in njihove medsebojne odvisnosti imamo sestoje za slučajne vzorce, kar nam omogoča dobiti cenilke za kote med baznimi smermi in s tem tudi za skalarne produkte.

• Title: Euclidean comparison of stands according to plant species

Abstract

In the article we describe a method of comparison of stands according to the appearance of plants. Contrary to methods which are or have been already in use, our comparison is purely euclidean: the stands are vectors in a multidimensional space (base lines are the plants) and the comparisons among them are expressed by their scalar products. We consider the stands in regard to plant species and their interrelations as random samples which enables us to get an estimate for the angles between the base lines and so also for necessary scalar products.
