Dendrometrical indices of trees of different ecological forms in urban ecosystems

The research objective was the assessment of dendrometrical parameters of trees of intraspecific Pinus sylvestris forms in Mikhaltsevsky grove of Vologda. The research problems were to make the laying of trial areas and to make the description of plantings of the object; to conduct the complex of landscape and taxation researches. During the re-search were put trial areas with carrying out the complex of works on them on landscape valuation. Dendrometrical indicators of wood trunks were measured. The classification of trees by crown forms was applied to the interpretation of material. Statistical processing was carried out on the basis of Ms Excel. The plantings of grove were repre-sented by Pinus sylvestris mixed with European fir-tree (age of 50-90 years, average diameter of the trunk at the height of 1.3 m - 27 cm, average height of trees was 25 m, the type of forest vegeta-tion conditions was pine wood). On the example of all considered Pinus sylvestris forms correlation dependences between dendrometrical indicators of trees were revealed: high correlation communica-tion between the number of boughs on one running meter, diameters at the basis of the knot and diam-eter of a crown. Larger branches and boughs at their smallest quantity on running meter were formed in wide crowned variation and the smallest with the greatest number on running meter - in nar-row crowned form. The size of the crown was ra-ther strongly interconnected with the formation of dendrometrical parameters of trees of Pinus sylvestris. At creation and operation of recreational forest-park facilities it is necessary to take such important diagnostic sign as character of habitus of Pinus sylvestris crown which in many respects is defining the state, esthetics and decorative effect of plantings into account.
