Abstract: Biomass dynamic monitoring and carbon storage quantitative estimation have become more and more important with the global climate change exacerbating. LiDAR(light detection and ranging)can be used as a tool to accurately acquire the three dimensional information of the forests, and usually has a high correlation with the biophysical parameters such as volume and biomass. It shows a great application potential of regional biomass continuous mapping and carbon storage estimation. In this paper, the composition and principle of a typical LiDAR system are introduced, and the various methods of biomass extraction and model fitting from different LiDAR data types are described, especially airborne LiDAR-based biomass estimations for the single tree and stand level. Finally, the limitation of biomass information extraction was discussed, and the future prospects of LiDAR development, such as the integration of data from various remote sensors and the most recent LiDAR hardware innovations, were presented.
