Plant root trait measurements raw data, 1962-2018, Island of Puerto Rico

This data package is a compilation of studies and raw datasets on root traits including root biomass, root nitrogen and phosphorus concentrations organized by different root diameters, species, soil depth, and forest types in Puerto Rico. The attached zip file contains a metadata document "archive metadata.docx" in Word document and PDF formats that describe the methods of data collection, the data sources and publications used in the synthesis, and information about the contents of the two CSV data files "root.shoot.ratio_PR.csv" and "Raw data.csv." Also included are a KMZ file with data collection locations and an additional CSV file with coordinates for each site of data collection organized by data author and year of publication. This dataset was originally published on the NGEE Tropics Archive and is being mirrored on ESS-DIVE for long-term archival Acknowledgement: USDA Forest Service - International Institute of Tropical Forestry.本数据包为波多黎各地区根系性状相关研究与原始数据集的汇编，涵盖根系生物量、根氮浓度与根磷浓度，并按根系直径、物种、土壤深度及森林类型进行分类编排。附件压缩包内含元数据文档"archive metadata.docx"，提供Word与PDF两种格式，用于说明数据采集方法、本综合研究所用的数据来源与参考文献，以及两个CSV数据文件"root.shoot.ratio_PR.csv"与"Raw data.csv"的内容信息。此外，压缩包还包含一份标注数据采集点位的KMZ文件，以及一份按数据作者与发表年份整理的各数据采集站点坐标CSV文件。本数据集最初发布于NGEE热带地区档案馆（NGEE Tropics Archive），现由ESS-DIVE进行镜像存档以实现长期留存。致谢：美国农业部林务局国际热带林业研究所（USDA Forest Service - International Institute of Tropical Forestry）
