Produkční a přírůstová charakteristika porostů ŠLP ML Křtiny na základě statistické provozní inventarizace
Kuličková, Barbora
The thesis examines the amount of growth and production characteristics of the set of stands, in which the transformation to the selective management method was started about fifty years ago. These are the parts of Klepacov and Pokojná hora, which are part of Habrůvka and the forest management complex ŠLP ML Křtiny. Repeated statistical inventory analysis using Field-map technology identified the necessary dendrometric variables. Some of them served to calculate the total current increment. Using the MS Excel program and the solver function, the coefficients of elevation functions for individual trees in the given sections were calculated. As a result of this step, the missing height, stock, enumeration of the basal area, the number of trees per hectare, etc. were calculated according to the model. On the basis of these data, individual production and growth characteristics were determined and then compared. These quantities were compared mainly at the level of inventory areas. Typology has also been omitted. Finally, the appropriate size of the optimal basal area was determined, taking into account the maximum value of the volume increment. In this case, a more detailed level in the form of individual trees was used outside the level of the inventory area, for the more precise determination of the values of the enumerating basal area. The basal area was evaluated in five variants according to the forest type (spruce, mixed, beech) and forest types (3S – fresh oak beech and 4S - fresh beech). From the individual tree level, the set value of the basal area was then recalculated to the target tree thickness in centimeters for possible practical use in selecting trees.
