Statistic Ground to Selection of Exposition-Orographic Groups of Silver Fir Forest Stands of the Ukrainian Carpathians

H.H. Hrynyk

Abstract


Theoretical bases and methodical approaches are presented concerning the evaluation of growth and productivity of mountain silver fir forest stands of the Ukrainian Carpathians taking into account exposition-orographic descriptions of places of their location and types of forests site conditions. As a result of researches the features of growth taking of mountain silver fir forest stands into account exposition-orographic descriptions of places of their location are analyzed, the proper tendencies and conformities to the law are set. On the basis of mathematic and statistic analysis, dividing of probed forest stands is carried out by exposition-orographic groups in the types of forest site conditions of C2-C3 and D2-D3; their graphic interpretation is presented.
