Sapling leaf and root traits from 6.6 km Jianfengling transect

These data were collected during the summer of 2017 in Jianfengling, Hainan Island, China. Juvenile tropical trees were sampled for leaves and root systems. Leaves and root systems were scanned, dried and weighed, and morphological traits were quantified with WinFolia (for leaves) and WinRhizo (for roots). About 1 kg of surface soil was collected from the area where root systems were excavated and collected. The soil samples (300 in total) were sieved and sent for laboratory analysis by the Guangzhou Xinhua Agricultural Limited Company in Guangzhou, China. <br>Plant functional trait and abiotiic soil chemistry data are provided in three separate files, one for leaf traits (CHINAROOTS_Leaf Traits.csv), one for root traits (CHINAROOTS_Root Traits.csv) and one including soils data (soil300.csv). Please see: Figshare_metadata.txt for complete variables descriptions for each datafile. <br>see www.experiment.com/chinaroots for a greater description of this research project.

本数据集采集于2017年夏季，采集地点为中国海南岛尖峰岭。研究选取热带幼树的叶片与根系作为采样对象，对采集的样品依次开展扫描、烘干与称重操作，并分别采用WinFolia（叶片）与WinRhizo（根系）软件量化其形态性状指标。同时从根系挖掘采样区域采集约1千克表层土壤样品，共计300份土壤样品经筛分后，交由广州新华农业有限公司（Guangzhou Xinhua Agricultural Limited Company）完成实验室分析。

植物功能性状与非生物土壤化学数据分为三个独立文件存储：叶片性状数据集CHINAROOTS_Leaf Traits.csv、根系性状数据集CHINAROOTS_Root Traits.csv，以及土壤数据集soil300.csv。各数据集的完整变量说明请参阅Figshare_metadata.txt文件。
