Abstract
The role of arboreous species in the functioning of lowland needle–fir broad–leaved forest landscapes of the southern Primorye was estimated. Forest stand structure as well as biocycle parameters (measured in main structure-functional points called parsells) of the needle–fir–broad–eaved forests and soils were investigated. The macroelemental composition of assimilating organs of trees (leaves and needles) and characteristics of leaf fall and litter were studied. It was established that broad–leaved trees with high ash content, especially hornbeam and Actinidia, significantly increase the capacity and speed of the biocycle. Therefore, such trees support the biological productivity and stable functioning of the studied landscapes.
