Experience in mathematical estimation of aboveground phytomass vertical fractional distribution in an oak stand of the forest steppe russian sfsr ussr

A new mathematical method for the estimation of the phytomass vertical-fractional distribution is supposed. The results on the vertical-fractional distribution of the phytomass, leaf surface of the aboveground part of the stand in the Quercetum aegopodiumosum are represented.
