Stav lesních porostů na výzkumných plochách v Krkonoších v letech 1976-1997
Original language description
Health state of maturing and mature Norway spruce (Picea abies L.), mixed spruce-beech and beech (Fagus sylvatica L.) stands was studied on 32 permanent plots (5th-8th altitudinal vegetation belt, pollution-damage zone A-C) in the Krkonoše Mts.during 196-1997. Analysis of air pollution and ecological factors was based on reactions of all single trees in the plot stand. Damage (indicated by defoliation) of a tree was classified every year according to Tesař, Temmlová (1971) scale for spruce and to Vacek, Jurásek (1985) scale for bee ch respective. Changes in the structure of ground (herb and moss) vegetation were studied using classification (TWINSPAN) and ordination (DCA) methods. Results were related to the defoliation. Three periods of tree damage were distinguished, according to the stage of damage. Highest resistance was documented in beech stands, lower in mixed spruce-beech stands, and the lowest in spruce stands. Tree damage was positively correlated with the altitude. ce stand
