Travnjaci duž beogradskih saobraćajnica - taksonomska i fitogeografska analiza

Abstract

Istraživanja obuhvataju uporednu taksonomsku i fitogeografsku analizu sastava travnjaka duž saobraćajnica Beograda. Korišćeni su rezultati florističkih istraživanja iz 2001. godine i rezultati dobijeni terenskim istraživanjima tokom 2019. godine. Komparativnom analizom uzetih rezultata došlo se do zaključka da je 2019. godine utvrđena manja heterogenost flornih elemenata i taksona biljaka na istraživanim travnjacima duž saobraćajnica Beograda u odnosu na stanje iz ranijeg peroda, što je posledica prisustva intenzivnijih mera nege istraženih travnjaka kao i znatnog uticaja antropogenog faktora koji su doveli do homogenizacije flore.

This study was done with the aim to comparatively analyze the taxonomic and phytogeographical spectrum of lawns along the Belgrade roads. The analysis was done using the results of a floristic research done in 2001, combined with results of the field research conducted in 2019. A comparative analysis of the obtained results has shown that a lower heterogeneity of the floral elements and plant taxa was recorded in the studied lawns in 2019, when compared to the previous research period. Such a reduction in heterogeneity is the result of more intensive measures of lawn care, and of a stronger anthropogenic influence, which has led to a homogenization of the lawn flora.
