Abstract

A new kind of quantitative model for assessment of state of Scotch pine tree stands growing in industrial polluted areas of Middle Urals is desribed. The model is based on the use of two types of indices - state indices and generalized state indices - which are calculated from morphological and physiological characteristics ( parameters ) of tree stands. Morphological parameters include average values of tree diameters, heights, and annual increments while physiological characteristics include chlorophyll a content and photochemical quantum yield of photosystem II in pine needles. It is shown that the use of the combination of diagnostic parameters as in the mod
