Spremembe gozdne vegetacije kot posledica učinkovanja onesnaženega zraka
Ivan Smole, Lado Kutnar, 1995

Povzetek: Podan je pregled dosedanjega dela, prvih rezultatov raziskave in smernice za nadaljne delo. Dosedanja dognanja niso jasno potrdila domneve, da se pritalna vegetacija pod vplivom onesnaženega zraka tudi v naših gozdovih spreminja. V bodoče se bo raziskava razširila na večje število objektov, stanje pritalne vegetacije pa bomo spremljali v daljših časovnih presledkih kot doslej.
Ključne besede: gozd, pritalna vegetacija, floristična sestava, onesnaženost zraka, emisija, onesnaženost tal, sprememba vegetacije, kvalitativna analiza, rastščni dejavnik, srednja vrednost, Slovenija, Srednja Evropa

Norway spruce (Picea abies (L.) Karst.) damage in the Zasavje district of Slovenia evaluated by two methods
Natalija Vidergar-Gorjup, Andrej Strniša, Franc Batič, 2000

Povzetek: The Zasavje district has been heavily affected by air pollution due to mining,the presence of a coal-fired power plant, and industry. The extent of forest damage differs according to location because of specific climatic and orographic characteristics. Norway spruce damage was estimated by two methods at 10 locations in the Zasavje district using the Slovenian forestry method for the estimation of forest damage (KOVA et al. 1995), and a Czech method forestimation of damage to the branching system and needle loss and discoloration (CUDLIN & CHMELIKOVA 1995). Comparison of the results obtained by the two methods gave similar damage assessments at heavily polluted sites, although the data obtained by the two methods differ due to several environmental parameters. The Czech method did not give as good results as wasexpected. A possible reason might be that spruce trees in the investigated locations are less damaged than those in the Czech Republic, where the method was developed.
Ključne besede: air pollution, Norway spruce, Picea abies (L.), tree damage, Zasavje, propadanje gozda, poškodovanost drevja, gozdno drevje, onesnaženost zraka, Zasavje, smreka, Picea abies (L.) Karst.
