Evaluating the Differences in Modeling Biophysical Attributes between Deciduous Broadleaved and Evergreen Conifer Forests Using Low-Density Small-Footprint LiDAR Data
Airborne light detection and ranging (LiDAR) has been used for forest biomass estimation for the past three decades. The performance of estimation, in particular, has been of great interest. However, the difference in the performance of estimation between stem volume (SV) and total dry biomass (TDB) estimations has been a priority topic. We compared the performances between SV and TDB estimatio...
متن کاملA robust approach for tree segmentation in deciduous forests using small-footprint airborne LiDAR data
This paper presents a non-parametric approach for segmenting trees from airborne LiDAR data in deciduous forests. Based on the LiDAR point cloud, the approach collects crown information such as steepness and height on-the-fly to delineate crown boundaries, and most importantly, does not require a priori assumptions of crown shape and size. The approach segments trees iteratively starting from t...
متن کاملMapping Above- and Below-Ground Biomass Components in Subtropical Forests Using Small-Footprint LiDAR
In order to better assess the spatial variability in subtropical forest biomass, the goal of our study was to use small-footprint, discrete-return Light Detection and Ranging (LiDAR) data to accurately estimate and map aboveand below-ground biomass components of subtropical forests. Foliage, branch, trunk, root, above-ground and total biomass of 53 plots (30 × 30 m) were modeled using a range o...
متن کاملEffects of Forest Age on Soil Autotrophic and Heterotrophic Respiration Differ between Evergreen and Deciduous Forests
We examined the effects of forest stand age on soil respiration (SR) including the heterotrophic respiration (HR) and autotrophic respiration (AR) of two forest types. We measured soil respiration and partitioned the HR and AR components across three age classes ~15, ~25, and ~35-year-old Pinus sylvestris var. mongolica (Mongolia pine) and Larix principis-rupprechtii (larch) in a forest-steppe ...
متن کاملAnalysis of Interaction Patterns between Vegetation Canopies and Small Footprint, High-density, Airborne Lidar
High resolution, small footprint, imaging lidar systems are becoming increasingly important for monitoring forest canopies. Without doubt they have the potential to dramatically change conventional methods of forest survey. It is often assumed that the first pulse of the laser beam interacts with the top of the vegetation canopy while the last pulse is assumed to come from the ground. In this p...
