LBA-ECO CD-08 Tree Diameter Measurements, Jacaranda Plots, Manaus, Brazil: 1999-2001

简介

本数据集提供了巴西马瑙斯以北 90 公里的 ZF-2 实验站一片茂密的热带湿润土地森林中树木的胸高直径(DBH)测量数据。DBH 的测量沿两条横断面(东西向和南北向)进行,这些横断面由蓝花楹项目(日本国家亚马逊研究机构(INPA)与日本国际协力机构(JICA)之间的协议)于 1996 年建立。每棵树的树干上都固定了一个金属测树带,每月用数显卡尺测量树干的周长生长情况。


样带尺寸为 20 米 x 2500 米,并按高原、坡地和白溪(靠近小溪的低地)分层。数据文件中还提供了地形位置、样带沿线距离、安装带的高度、当地树木名称以及实地考察记录。测量时间为 1999 年 6 月至 2001 年 12 月。


此数据集有四个逗号分隔格式(.csv)的数据文件。


摘要

Files 1 and 2 follow the same organizational scheme:

 CD08_Dendrometers_Jacaranda_Edgard_EW.csv and CD08_Dendrometers_Jacaranda_Edgard_NS.csv

COLUMN COLUMN HEADING Units/format Description
1 PI Name of the principal investigator for whom the data were originally collected
2 Tree_ID Tree identification
3 Local_name Local name of the tree species where identified
4 Transect Location of the tree on either the North-South (N-S) or East-West (E-W) transect set up in the Jacaranda plots
5 UA Sampling unit (unidade de amostra in Portuguese) each 2500-m by 20-m transect was divided into 125 20-m by 20-m units numbered sequentially
6 Distance m Distance along the transect reported to the nearest 20-m
7 Topography Location in terms of topography: plateau, slope or baixio which refers to a lowland position associated with small streams
8 DBH_init cm Initial DBH reported in centimeters (cm)
9 Family Identification of the tree to scientific family
10 Genus Identification of the tree to genus
11 species Identification of the tree to species
12 to 28 YYYYMMDD mm Columns 12 through 28 are labelled with the sampling date in the format YYYYMMDD and report the dendrometer reading on that date in millimeters (mm)
29 Notes Notes from field observations on the condition of the tree and the dendrometer


Files 3 and 4 follow the same organizational scheme:
