Proizvodna sposobnost gozdnih rastišč, ki jih poraščajo smrekovi in bukovi gozdovi ter njihova proizvodna zmogljivost v optimalni razvojni fazi

Kotar, Marijan (author)

Članek predstavlja rezultate analiz, ki so bile opravljene na 18 rastiščnih enotah na katerih uspevajo bukovi sestoji, in na 10 rastiščnih enotah, kjer gradi gozdove smreka. Sestoji so razmeroma enomemi, glede starosti pa bolj ali manj raznodobni. Proizvodno sposobnost rastišč lahko ugotavljamo s pomočjo rastiščnega indeksa (site index). V članku je prikazano gibanje tekočega volumenskega prirastka v zadnjih treh desetletjih. Prirastek ima pozitiven trend na 68 % analiziranih ploskvah pri smreki ter na 28 % pri bukvi. Skupaj je bilo analiziranih 90 ploskev pri bukvi in 50 ploskev pri smreki. Pozitiven trend prirastka pri tej starosti sestojev je nenavaden. Vzrok za spremenjen način v rasti teh sestojev lahko povezujemo s spremembami v rastišču ali pa je posledica velike raznodobnosti.

• Title: Site productivity on spruce and beech sites and current annual increment of their stands in the optimal phase

Abstract

The author presents the results of investigation which was carried out in beech and spruce stands on their natura! sites. The determining of site productivity by means of site index and total volume production was successful in homogeneous but uneven-aged stands. In this case should be used the top-height at 100 years. The author has established that the stands which are used for determining of site index and site productivity should be older then 100 years. The convergence of height curves according to sites is different. The current annual increment in the studied stands has increased in 68 % of analysed spruce plots and in 28 % of analysed beech plots. This increase in the stands age from 94 to 196 years is likely related to changes in site productivity.
