Pattern of Biomass Partitioning into Fractions of Boreal Trees

Аннотация

Ratios between above- and underground phytomass of tree organs were studied for different forest types. The partitioning of phytomass into tree fractions was described using rank distributions characterizing the relationships between the resource volume available for each tree organ and the ranks of biomass fractions. Species-specific parameters of biomass partitioning into tree organs were calculated, and the dependences of these parameters on the forest type and tree size were revealed. Independent verification of the biomass distribution model was performed.
