5) replacement of fixed trees
固定样木复位
1.
To solve the difficulty of replacement for fixed sample plots and the lower precision for fixed sample tree mensuration in the system of national forest resources continual inventory,the precision of inventory can be improved using portable GPS in the position of fixed sample plots,using total station to mensurate the height of fixed trees and using compass in the replacement of fixed trees.
为解决国家森林资源连续清查体系中固定样地复位较难、固定样木测定精度不高的问题,采用手持GPS对固定样地定位、全站仪对固定样木测高、罗盘仪对固定样木复位的方法可以提高调查精度。

补充资料:阿诺德树木园
美国哈佛大学所属的植物学综合研究机构,以引种栽培乔、灌木植物著称。建于1872年 3月29日。有树木园107.2公顷,栽培乔、灌木植物6215种(包括变种和品种),繁殖温室700平方米,试验苗圃60.3公顷。馆藏蜡叶标本130余万份,其中野生植物标本约113万份,栽培乔、灌木植物标本约17万份。设有植物分类、植物化学和遗传育种等实验室,定期出版《阿诺德树木园植物学报》和《阿诺德树木园》等杂志。树木园引种栽培乔、灌木植物的种类居世界各国植物园之首。在引种和研究亚洲东北部的植物,特别是中国的植物方面,享有盛名。经该园首次引入美国栽培的经济和园林观赏乔、灌木树种达 700多种(包括变种和品种)。对木兰科、槭树科、杜鹃花科、柳属、海棠属、山楂属、丁香属和矮生松柏类等植物搜集较齐全,其中丁香属植物搜集近500个品种。
