METHOD OF SITE CLASS DETERMINATION OF COMPLEX, MIXED, UNEVEN-AGED PLANTATIONS Russian patent published in 2014 - IPC A01G23/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of forestry and forest biogeocenology and can be used for the forest resource inventory and organisation of forestry during forest management fieldwork. The method comprises aerial photography, interpretation of a contour base of taxation plots on aerial photographs, field inventory of plantations and treatment of materials of forest inventories. The interpretation of the aerial photographs is carried out by a landscape method. The assessment of productivity of plantations is carried out in complex taking into account growth energy of all components of forest stands of plantations of forest elements to obtain the integrated assessment on the landscape base of the degree of viability and growth rate of complex, mixed and uneven-aged forest stands through recording the contribution to the overall productivity of individual completeness and reserves of each forest stand of the forest element by the index of growth energy of a plantation E. The index of growth energy of a plantation E is determined by the table, in which basis there is the ratio of the total reserves of all tiers of plantations and the total relative completeness of all forest stands of the forest elements of the same plantation.

EFFECT: method provides enhancement of accuracy and quality of assessment of plantation productivity.
