The comprehensive value of the planted seedlings under forest in the designed scheme in Beijing were assessed by applying VE and VA methods. It was indicated that the value of the seedlings under ecological forests followed the order of Quercus variabilis, Broussonetia kazinoki, Cotinus coggygria, Acer truncaturn etc. It was concluded that in the forestry management, comprehensive values should be considered to select seedling species with high values for regeneration under forests.
评价结果认为,在以生态公益林定位的森林经营中,人工林下更新幼苗的综合价值依次是栓皮栎、构树、黄栌、华北五角枫等,所以在林下层苗木的经营选择中应该按照这些树种的综合价值来进行苗木的选择和操作。

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.
本研究於阿里山地区设置样区,针对台湾赤杨、柳杉、红桧等树种进行立木树高之量测,配合该样区之空载光达影像资料,建立树冠高度模型(Canopy height model, CHM),探讨空载LiDAR在森林地区对於单木树高与林分高的量测情形;单株立木高系以样区立木位置为中心,萃取0.5 m 圆形环框范围内之CHM平均值为其推估值;光达林分高则以6种林分面积(5 m×5 m、10 m×10 m、12.5 m×12.5 m、15 m×15 m、17.5 m×17.5 m、20 m×20 m)萃取范围内之CHM平均值为其推估值。

We developed the spatial information, which included DTM, topography, slope, aspect, altitude, temperature, precipitation, light soil types, soil texture, administrative zoning, forestry zoing, stream transportation network. The colored aerophotos were scanned and corrected to be orthogonal images. Then, land cover were interpretated and land-use mapping. Ecological site quality of Chamaecyparis formosensis were evaluated for productivity. Habitat suitability index of warbers and guid were evaluated for biodiversity of landscape. The restoration strategies of collapsed area after Chi-Chi earthquake were developed by land evaluation.
