Ověření experimentální metodiky vyhledávání hnilob založené na impedanční tomografii v porostech smrku ztepilého (Picea abies L.)

The purpose of this Bachelor thesis was to monitor health of the Norway spruce (Picea abies L.), which is currently strongly endangered by biotic and abiotic factors. For the health detection of the woods are used non-destructive diagnostic machines. Measuring were in the territory of the Training forest enterprise Masarykův les Křtiny, Polesí Habrůvka. For the measuring were used acoustic tomography, which is based on passage of sound waves and electrical impedance tomography which is also used for detection rot electric resistance. Using this tomography was evaluated the presence of the rot in the trunk and its range. Total number of the trees measured by acoustic tomography was 30 trees, 15 trees were measured by electrical impedance tomography. For determination of the accuracy of measurement electrical impedance tomography, were compared the results with the specific tree cut-outs. For measurement of acoustic tomography was observed velocity changes because of the damages. Thanks to the detection rots and cavities in the trunk was also partly determined the stability of the tree
