Burned Forest Vegetation Recovery Monitoring Method Using Satellite Remote Sensing

摘要

To the monitoring technology needs for the effect on forest growth and restoration of alpine region by forest fires, Yajiang County in Sichuan province of People Republic of China has been selected as the experimental area. By means of the analysed results on the factors, such as the vegetation spectral characteristics, Normalized difference vegetation index(NDVI) of the burned forest area(samples of different severity (light, moderate and severe) have been selected) and normal vegetation region by using the time-series images of the NO.1 high-resolution satellite (GF-1).The results showed that the trends of the burned forest recovery was correlated with the damage degree by forest fire. The more serious forest burned, the slower the restoration.
