Razvoj gozdnega sestoja jelke na raziskovalni ploskvi na Menišiji : diplomsko delo - visokošolski strokovni študij

Ileršič, Martin (author), Hladnik, David (mentor)

Leta 2007 smo ponovili izmero na raziskovalni ploskvi 92 v jelovo bukovem sestoju na Menišiji, veliki 2 ha. Na podlagi podatkov o zaporednih merjenjih dreves smo ocenili razvoj gozdnega sestoja. Izmerili smo premere dreves, višine jelk ter popisali njihove kakovostne znake. Analizirali smo spremembe drevesne sestave, spremembe frekvenčnih porazdelitev dreves po debelinskih stopnjah, ocenili razvoj višin in razlike v sestojnih višinskih krivuljah, spremembe lesnih zalog ter osutosti krošenj jelke. Osutost krošnje ima močan vpliv na debelinsko rast jelke, stopnje osutosti pa se razlikujejo po slojih.

Abstract

In 2007 we have repeated the measurement of trees on a research plot in silverfir and beech stand in Menišija, which is 2 hectares in size. We have made an evaluation of the development of the forest stand on the basis of dataon succesive measurement. We have measured diameters of trees and heights of silver firs, and made an assessment of their quality signs. We made an analisys of the tree species structure, changes of frequency distribution of trees by diameter distribution, height distribution, growing stock, state of silver-firs crown. The tree crowns needle loss has major influence on the intensity of the diameter increment and degrees of tree crowns needle loss differ according to vertical stand layer.
