Abstract:The effective absorption of radiation in the visible spectral range by chloroplasts and the high reflectance of the near infrared radiation by the cell walls of the plants are appropriate spectral features to estimate green biomass and LAI and etc. In this paper,forest biomass in western Guangdong,China was estimated by using Landsat TM data.First,field measurements of stem volume( V ) were obtained from 67 plots(30m×30m),including 28 plots for broadleaved forests and 37 plots for coniferous forest...
