Různé způsoby stanovení střední tloušťky a jejich vliv na výši zásoby porostu stanovenou metodou jednotných objemových křivek

It was detected that different ways of the mean diameter have no influence on the stand volume, which was estimated by the method of uniform volume curves. Field works were situated in property of town Planá in Pilsen region. The stand volume of thirteen stands in maturity age (more than 3 hectares area of stands, management set of stands 433, forest type 3K3) was estimated during field works. These volumes were estimated for each tree species and whole stand by the method of uniform volume curves and also for comparison by the method of volume tables. Four ways of the determining the mean diameter (Weiss´s, quadratic and two modifications by the Sedmák et al., 2015) were compared. There were not detected any statistical differences after data analysis. It can be stated that different ways of the mean diameter determining have no effect for the estimation of tree species volume and stand volume estimated by the method of uniform volume curves
