METHOD OF DETERMINING RATING OF TYPE OF SPECIES FOR LANDSCAPING PLAN Russian patent published in 2015 - IPC A01G23/00 

FIELD: agriculture.

SUBSTANCE: invention relates to forestry and can be used for planning events for landscaping urban areas. The method comprises making a catalogue of tree species of the surveyed urban settlement with known environmental conditions and the corresponding area of the reference site. The measurements are performed by technical means: a digital camera; a digital videospectrometer; an altimeter; a counter of set of parameters that determine the amount of oxygen-producing biomass of each species of plants: cross-sectional area of the crown S, m²; the density of the crown as average weighted spatial frequency F_av [1/m] of function of the signal of its image I (x, y), colourity of the crown as the average weighted wavelength χ_av [nm] of spectral brightness coefficient, the average height h [m] of plantations of this species relative to the number of healthy N_i trees to their total number N of this species, the rating of the measured parameters relating to their values for the reference sites, ranking the indicators in descending order of their importance in the volume of the producing phytomass, calculation of function of ranking score R_i as average weighted sum of the relative indicators of each type of the species: where: ω₁, ω₂, ω₃, ω₄, ω₅ are weight coefficients of significance, making of the final table of rankings the types of species.

EFFECT: method enables to ensure the resistance of urban landscaping to technogenic loads.
