Seasonal patterns of canopy structure, biochemistry and spectral reflectance in a broad-leaved deciduous Fagus crenata canopy

摘要

The reflectance of a deciduous forest varies from spring to autumn owing to phenological or seasonal changes in the biophysical or biochemical attributes of the canopy. During the growing season in a broad-leaved deciduous stand of Japanese beech (Fagus crenata), we measured the continuous reflectance factor in the visible to near infrared spectrum (380-900 nm) from a tower and measured biophysical and biochemical attributes of the canopy (leaf area index (LAI), fraction of absorbed photosynthetically active radiation (fAPAR), and chlorophyll content.
