; Finally, based on the characteristic variable and the crown area of the single tree biomass measured point cloud of individual tree segmentation, stepwise regression (StepWise) construct a single model tree biomass different stands.
Finally, based on the point cloud feature variable of single wood division and the crown area and measured single wood biomass, the single-wood biomass model of different forest fractions is constructed by step-by-step regression (stepwise).
Finally, based on the characteristic variables of point cloud and canopy area of single tree segmentation and the measured biomass of single tree, stepwise regression was used to build the biomass model of different stands.<br>
