资源简介：
We complied a global database of Paired Resorption Efficiency of Nitrogen and Phosphorus (PRENP, Version 1.0) in leaves of terrestrial plants based on literature surveyed via Web of Science (http://isiknowledge.com), Google Scholar (https://scholar.google.com) and the China National Knowledge Infrastructure (http://www.cnki.net). The key words ‘nitrogen resorption’ and ‘phosphorus resorption’ were used to search published studies of leaf NRE and PRE. Data were included only when NRE and PRE were measured simultaneously. To avoid misattributing natural nutrient limitation due to anthropogenic disturbances, we excluded data for intensively managed ecosystems (e.g., agroforest, fertilized plantations, sown pastures, croplands and urban forests). Overall, our database includes observations of leaf NRE and PRE across 171 sites. For each site, we first averaged values of NRE (NRE<sub>dom</sub>) and PRE (PRE<sub>dom</sub>) for all reported dominant species, respectively. If data on several forest stands or grassland plots were reported at the same site, NRE<sub>dom</sub> and PRE<sub>dom</sub> were averaged before computing NRE<sub>dom</sub>/PRE<sub>dom</sub>. Site-averaged NRE<sub>dom</sub>/PRE<sub>dom </sub>was then calculated as an indicator of relative nutrient limitation. Please find more information in the Nature Geoscience paper by Du et al.
