| Abstract: | The small footprint LiDAR can directly access to forest vertical and horizontal structural parameters,therefore it is widely used to estimate the height,biomass,canopy density,and so on. In this paper,the application of LiDAR in forest biomass estimation was analyzed. According to different scales,the forest biomass inversion techniques and methods of single and plot level were analyzed in detail respectively. Then,the potential of the combination of small footprint LiDAR and other remote sensing data were elaborated. Based on the above analysis,the problems in the the application of small footprint LiDAR in forest biomass estimation were summarized and the prospect of the research direction was forecasted. |
