Abstract: This paper summarizes the application of forest parameter estimation with the airborne laser radar,such as tree height,canopy density,growing stock,biomass and so on. Accuracy of forest parameters estimated and its influencing factors is summarized and analyzed. The key technologies are summarized about forest parameters estimated based on airborne laser radar data,such as methods of filtering points cloud based on geometric characteristics of LiDAR data,methods for forest parameters estimated based on the intensity information,methods of processing the full-wave form LiDAR data and fusion technique between LiDAR data and multi-spectral imaging. The paper described their status,scopes of their application and problems.

Key words: LiDAR, forest parameters, points cloud, intensity information, full-wave form, data fusion
