Size and quality characteristics of wood stockpine stands and their relation to taxation parameters

Abstract

The taxation cost of the growing stock of wood is a minimum value, which determines the profitability of forestry in Belarus. In many ways this value depends on the size characteristics of the wood stock. These characteristics are determined by taxation indices, which, in turn, through the forestry measures can be affected by people. Therefore in this study we set a goal – to reveal the dependence of size and qualitative characteristics of growin g tree stock on its taxation indices. The data from taxation on 26 plots of mature pine stands of different forest types were used to study the dependence of size and quality characteristics of the stock of pine stands on their inventory indices. Factors (stand characteristics) we re identified to determine the size and patterns of formation of qualitative characteristics of stocks, they are influence these long-indicators. The first priority was to identify those factors which may aff ect the forehead-century as a result of economic activity. According to the results of the correlation analysis four inventory indices were selected: the average age of the stand, its density, relative fullnessand forest type. As a result of the regression analysis were obtained depending on the model size and quality characteristics of the stand from the previously selected major forest indices. The coefficients of determination were analyzed and we can conclude that the regression-equations describe well analyzed according to ( R{2} for most size-quality characteristics of greater than 0.7). These models can be used in the design of forest management activities aimed at building stands with the required size and quality characteristics of wood stock.
