Abstract:The greenness lndices, albedo and temperature field of underlying surface with different forest cover percent were analysed using 5 channels data by NOAA satellite AVHRR transducer. The results showed, The forest cover percent was positive correlation with greenness indices; The greenness indices was negative correlation with the albedo; The greenness indices was negative correlation with maximum temperature; The albedo was positive correlation with maximum temperature. A new method was provided by using NOAA satellite data for studying the effects of forest on environment in the future.
