Vegetacija, ekološki dejavniki in njihova soodvisnost v primeru cestnih brežin

The work deals with vegetation and ecological factors of the roadside slopes as well as their reciprocalinfluences. Vegetation was inventoried using the standard method and soil samples as well as temperaturewere analysed. Canonical Correspondence Analysis method reveals that it is water regime that mostlyinfluences vegetation, especially depends on steepness, which determinates the amount of receivedprecipitation. Soil reaction is also important, due to the fact that soil is generally alkaline and poor. Therelevčs were classified into 8 communities using hierarchic classification method and deductive methods.Vegetation is most diversified on the slope with most severe conditions.Delo obravnava vegetacijo in ekološke dejavnike na cestnih brežinah ter njihove medsebojne vplive. Postandardni metodi je bila popisana vegetacija, analizirani so bili vzorci tal in temperatura. Metoda kanoničneskladnostne analize (CCA) kaže na to, da na sestavo vegetacije najbolj vpliva vodni režim, ki je odvisenpredvsem od naklona, ki določa količino prejetih padavin. Pomembna je tudi reakcija tal, ki so na splošnobazična in siromašna. Z metodo hierarhične klasifikacije in z deduktivno metodo smo popise uvrstili v 8združb. Vegetacija je najbolj pestra na brežini z najslabšimi razmerami
