Ocena zanesljivosti podatkov o gozdnih sestojih na podlagi kontrolne vzorčne metode v GGE Semič : diplomsko delo (visokošolski strokovni študij)

Križan, Stanislav (author), Hladnik, David (mentor)

Diplomsko delo obravnava oceno zanesljivosti podatkov o gozdnih sestojih na podlagi kontrolne vzorčne metode v gozdnogospodarski enoti Semič. Na osnovi podatkov iz stalnih vzorčnih ploskev, ki so bile merjene leta 1995 in 2005, smo ocenili, kako zanesljivo so potekale meritve na vzorčnih ploskvah in predvsem, pri katerih drevesnih vrstah so bile odkrite spremembe. Prav tako smo ocenjevali, katere podatke in informacije o zgradbi sestojev in njihovi pestrosti je mogoče pridobiti na podlagi kontrolne vzorčne metode. Za posamezne stratume smo izračunali ocene o sestojni zgradbi in pestrosti sestojev in te ocene primerjali s podatki o popisu gozdov. Primerjava s podatki o popisu gozdov razkriva razlike, ki so posledica drugačnega načina pridobivanja podatkov. Kontrolna vzorčna metoda je ob zadostnem številu vzorčnih ploskev po posameznih stratumih primerna za spremljanje razvoja gozdov in ocenjevanje sestojnih parametrov.

Abstract

The thesis deals with the evaluation of reliability of data about forest stands on the basis of control sampling method in the Semič Forest Management Unit. On the basis of data from permanent sampling plots, which have been measured in 1995 and 2005, we estimated how reliable the measurements on sampling plots were and above all which tree species have been subject to separate changes. We also evaluated which data and information about structureof the stands and their diversity is possible to be acquired on the basis of control sampling method. We calculated the estimation about stand structure and species diversity of the stands for individual strata and then we compared our estimations with the data from the forest management plan. This comparison revealed differences, which are also the result of different ways of gaining data. If we have sufficient number of sampling plots with regard to individual strata the control sampling method is suitable for observing the development of forests and evaluating standsć parameters.
