For the DPPH free radical scavenging, their EC50 values are 19.05 mg/ml and 15.61 mg/ml respectively, but their anti-oxidant capacities are 40 to 60 % higher than fresh ones. Hot water extracts of Boehmeria nivea root experienced sun dry treatment have a better ability to scavenging ABTS free radical (EC50=34.16 μg/ml)when compared to that of fresh root, which only have one tenth anti-oxidant ability left.

In order to analyze the airborne LiDAR data corresponding to single trees and stand heights in the forestry area, we set up samples to measure tree heights of Alnus formosana, Cryptomeria japonica, and Chamaecyparis formosensis in the Alishan area. We build the Canopy Height Model based on the data from the airborne laser scanning system. Single Tree heights were estimated by averaging the CHM values within a 0.5m radius, and six different sizes of sample stands (5×5, 10×10, 12.5×12.5, 15×15, 17.5×17.5, and 20×20) were set up to extract the average heights within the area as the calculated value.
