Vpliv onesnaževanja ozračja na rastnost odraslih smrekovih sestojev - metoda kvantificiranja ogroženosti fizioloških funkcij gozda

Ferlin, Franc (author)

Raziskava je bila zasnovana v petih smrekovih sestojih predalpskega, alpskega in preddinarskega dela Slovenije. Proučevane vzorčne populacije obsegajo 200 do 250, skupaj 1200 živih dreves na 25 raziskovalnih ploskvah, vključujoč tudi izločena drevesa. V prispevku je proučen vpliv neposrednega in posrednega onesnaževanja ozračja na prirastne trende in rastnost odraslih smrekovih sestojev. Uporabljena je izvirna metoda kvantificiranja sestojnih (pri)rastnih izgub. Posebej so bili analizirani tudi trendi zdravstvenega stanja sestojev po letu 1996. Prikazan je bil poskus celovitejšega ovrednotenja ogroženosti fizioloških funkcij gozda. Nakazane so bile možnosti za uporabo metode pri vrednotenju ogroženosti drugih funkcij gozda. Podane so bile nekatere splošne gozdnogojitvene usmeritve za gospodarjenje v imisijsko ogroženih smrekovih sestojih.

• Title: The impact of air pollution on productivl'iy of mature Norway spruce stands -a method for the quantification of endangerment of physiowgical forest functions

Abstract

Five Norway spruce stands in the pre-Alpine, Alpine and pre-Dinaric regions of Slovenia were studied. Sample populations included between 200 and 250 trees each, a total of 1200 growing trees on 25 research plots, including trees which had been thinned or self thinned. The study was aimed at analyzing the impact of direct and indirect air pollution on growth trends and productivity of mature Norway spruce stands by the use of an original quantification method for the evaluation of stand growth losses. The trend of health condition of stands since 1986 was also examined. An attempt was made to comprehensively evaluate the endangerment of physiological functions of forest. The results are presented as a guide to applying the method for an assessment of the endangerment of other forest functions. Some general silvicultural guidelines for florist management in Norway spruce stands endangered on account of air pollution are presented.
