Diameter-at-Breast-Height Estimation is a prerequisite in various allometric equations estimating important forestry indices like stem volume, basal area, biomass and carbon stock. LiDAR Technology ha...
IMPACTS OF TREE HEIGHT-DBH ALLOMETRY ON LIDAR-BASED TREE ABOVEGROUND BIOMASS MODELING
tree aboveground biomass lidar allometric equations simulation regression
2016/11/30
Lidar has been widely used in tree aboveground biomass (AGB) estimation at plot or stand levels. Lidar-based AGB models are usually constructed with the ground AGB reference as the response variable a...
Accuracy of Structure from Motion models in comparison with terrestrial laser scanner for the analysis of DBH and height influence on error behaviour
hand-held digital camera point cloud stem optimization image segmentation photogrammetry
2016/9/2
With the advantage of Structure from Motion technique, we reconstructed three-dimensional structures from two-dimensional image sequences in a circular plot with a radius of 6 m. The main objective of...
Proliferative enteropathy (PPE)-induced changes in the expression of DBH, VAChT and NOS in the neurons of intramural ganglia of the porcine ileum
ileum enteric nervous system biologically active substances

As enteric neurons are regarded to be highly adaptive in their response to various pathological states,
including inflammation, it appears to be of interest to study the chemical coding of neurons i...
Study on DBH-structure of Populus euphratica and Their Spatial Distribution in the Lower Reaches of the Tarim River
胸径结构 胡杨 塔里木河 林木分布

采用“面”上宏观调查与“点”上典型研究相结合, 集中对塔里木河下游阿拉干断面100 hm2的胡杨(Populus euphratica)林木分布与胸径结构进行了调查。结果发现, 在距河道0-20 m的范围内, 胸径为0-4 cm的幼龄胡杨占最多, 达到13.24%。以后随着离河道距离的增加, 幼龄胡杨所占比例逐渐减小。胸径分布范围简单, 胸径为16-36 cm的林木株数在胡杨林中所占的比例最多。另...
