摘要：
The polarimetric characteristics of early- and late-stage deforestation areas were examined using PALSAR-2. An early-stage deforestation site, where the fallen trees had been left on the ground, showed an increase in sigma(0)(surface) of 2.9 dB, and decrease in sigma(0)(volume) of 1.4 dB. This induced the 0.9 dB increase in sigma(0)(HH). A late-stage deforestation site, where the fallen tree had been removed, showed an increase in sigma(0)(surface) of 2.3 dB, and a decrease in sigma(0)(volume) of 6.4 dB. This induced the 6.1 dB decrease in sigma(0)(HV). Polarimetric analysis clarified the scattering mechanism for the early- and late-stage deforestation areas.
