这篇文章首次按学名和国家分布概述了所有已知树种，并描述了一个在线数据库--GlobalTreeSearch--提供访问这些信息的途径。根据我们对已公布数据来源和专家意见的综合分析，目前科学上已知的树种数量为60,065种，占所有被子植物和裸子植物物种的20%。近一半的树种(45%)仅见于10个科，其中树木最丰富的3个科是豆科、茜草科和桃金娘科。从地理上看，巴西、哥伦比亚和印度尼西亚是树种最多的国家。国家特有树种最多的国家反映了更广泛的植物多样性趋势(巴西、澳大利亚、中国)或孤立导致物种形成的岛屿(马达加斯加、巴布亚新几内亚、印度尼西亚)。近58%的树种是单一国家特有树种。我们的目标是将GlobalTreeSearch作为一种工具，在全球、区域和/或国家层面上监测和管理树木物种多样性、森林和碳储量。它还将被用作全球树木评估的基础，该评估旨在到2020年评估世界上所有树种的保护状况。
This article presents, for the first time, an overview of all known tree species by scientific name and country level distribution, and describes an online database-GlobalTreeSearch-that provides access to this information. Based on our comprehensive analysis of published data sources and expert input, the number of tree species currently known to science is 60,065, representing 20% of all angiosperm and gymnosperm plant species. Nearly half of all tree species (45%) are found in just 10 families, with the 3 most tree-rich families being Leguminosae, Rubiaceae, and Myrtaceae. Geographically, Brazil, Colombia, and Indonesia are the countries with the most tree species. The countries with the most country-endemic tree species reflect broader plant diversity trends (Brazil, Australia, China) or islands where isolation has resulted in speciation (Madagascar, Papua New Guinea, Indonesia). Nearly 58% of all tree species are single-country endemics. Our intention is for GlobalTreeSearch to be used as a tool for monitoring and managing tree species diversity, forests, and carbon stocks on a global, regional, and/or national level. It will also be used as the basis of the Global Tree Assessment, which aims to assess the conservation status of all of the world's tree species by 2020.
