Výpočet radiace v lesních porostech na základě dat leteckého laserového skenování
 Patočka, Zdeněk
Leaf area index (LAI) is the most important variable influencing the penetration of solar radiation beams through the forest stand. Currently, the airborne laser scanning, as new indirect method, suggests itself for estimation of LAI. LAI was measured terrestrially using the hemispherical photographies analysis and compared with LiDAR Penetration Index - LPI. There were created several regression models describing the dependence of LAI and LPI with coefficients of determination from 0.71 up to 0.81. Leaf area index was also applied to the Beer-Lambert law for calculation of the solar radiation in forest stands. Practical application possibilities of LPI in forestry (estimation of stocking, optimization of shelterwood cuttings etc.) have been described in conclusion of this diploma thesis.
