Estimating forest biomass at region scale quickly、quantificationally、accuracily is an important problem among ecosystem functions evaluation and carbon storage studys. Remote sensing technique can obtain forest biomass continuous distribution information on surface in time and accuracily in large area, because of its wide range of observation、large amount of information、quick information access. This study using Landsat 8 OLI multispectral imagery、small-footprint LiDAR data and plot survey data, firstly, es...
