Abstract

Školska dvorišta te zelene površine i biljne vrste koje se unutar njih nalaze mogu pozitivno utjecati na kvalitetu nastave osnovnoškolske djece. Kako bi se ispitao utjecaj veličine školskog dvorišta na brojnost i sastav dendroflore školskih vrtova, provedeno je istraživanje na 40 osnovnih škola na području grada Zagreba. Školska dvorišta su na osnovu ukupne površine podijeljena na mala, s površinom manjom od 16.000 m2 i velika, s površinom većom od 16.000 m2 . Na osnovu t-testa utvrđeno je da postoji signifikantna razlika između malih i velikih školskih dvorišta po ukupnom broju biljnih vrsta. Mala školska dvorišta imala su značajno veći ukupan broj biljnih vrsta. Isto tako, utvrđena je negativna korelacija između površine parcele i ukupnog broja biljnih vrsta tj. s porastom površine parcele smanjuje se broj biljnih vrsta i obrnuto. Pozitivna korelacija utvrđena je između broja zastupljenih primjeraka i vrsta stabala i grmova, odnosno sa porastom broja vrsta raste i broj zastupljenih primjeraka. Što se tiče sastava vrsta, u malim školskim dvorištima prevladavale su vrste Betula pendula, Carpnus betulus i Fraxinus excelsior od stabala te Lonicera pileata, Taxus baccata i Spiraea x vanhoutei od grmova. Betula pendula je bila dominantna vrsta i u velikim školskim dvorištima gdje su prevladavale vrste Pinus nigra i Fraxinus americana od stabala odnosno Berberis thunbergii, Spiraea x bumalda i Prunus laurocerasus od grmolikih vrsta. Provedenim istraživanjem je utvrđeno da veličina školskog dvorišta nije ograničavajući faktor za kvalitetan školski vrt, sa stajališta dostupnosti biljnih vrsta.

Abstract (english)

School yards, green surfaces and plants in them can positively affect the quality of teaching of primary school children. A survey was conducted in 40 primary schools in Zagreb area, to examine the impact of the size of the school yard on number and composition of dendroflora in school yards. School yards, based on total area, were divided into small - with an area of less than 16.000 m2, and large – with an area larger than 16.000 m2. Based on t-test, there was a significant difference in the total number of plant species between small and large school yards. Small school yards had significantly higher total number of plant species.
Also a negative correlation was found between plot area and total number of plant species, as the plot area increases, the number of plant species decreases and vice versa. A positive correlation was found between the number of specimens and species` richness; as the number of species increases, so does the number of specimens represented. In small school yards predominat tree species were Betula pendula, Carpnus betulus and Fraxinus excelsior while predominat shrub species were Lonicera pileata, Taxus baccata and Spiraea x vanhoutei. Dominant tree species in large school yards were Betula pendula with Pinus nigra and Fraxinus americana predominating, compared to small school yards. Dominant shrub species in large school yards was Berberis thunbergii, Spiraea x bumalda and Prunus laurocerasus. From the point of plant species availability, it has been found that the size of the school yard is not a limiting factor for a quality school garden.
