Above-Ground biomass estimation of larch based on terrestrial laser scanning data

Terrestrial laser scanning (TLS) can acquire high-precision point cloud data within a short time span and it has received a lot of attention in the study of forest structures. In this study the height and diameter at breast height (DBH) of larches are estimated based on TLS data and then the larch allometric model is used to estimate the above-ground biomass (AGB) of single tree in plots located at Saihanba National Forest Park, Heibei Province, China. The results show that DBH and tree height can be estimated with relatively higher accuracies with R 2 values of 0.95 and 0.80, respectively, and root mean squared error (RMSE) value of 2.91 cm and 1.54 m, respectively. In addition, the AGB is estimated based on the retrieved DBH and tree height. The results show that tree parameters and AGB can be estimated from TLS data.
