Understanding the determinants of species distributions is a central topic in ecology. Competition, stress tolerance and colonization, respectively represented by Grime's competitor (C), stress‐tolerator (S) and ruderal (R) schemes, are three important functions that interactively influence plant distributions. In this study, we compiled a dataset of 2645 vascular plant species to explore the roles of the CSR strategies in global plant distribution. We analyzed the associations between the CSR scores and species range size with phylogenetic generalized least square (PGLS) models and phylogenetic path analysis, both of which accounted for the effects of species phylogenetic relatedness, longevity and growth form. The functional strategy‐range size associations differed across different distributional ranges and growth forms. Specifically, species global and native range sizes were positively associated with the R score; species naturalized range size was positively associated with the C score; and all range‐size measurements were negatively associated with the S score. These patterns were mostly driven by herbs but not shrubs or trees. For species global and native‐range distributions, the patterns of shrubs were even opposite to those of herbs. Our work emphasizes the importance of distinguishing the functional strategy‐distribution associations between different distributional ranges and growth forms for ecosystem conservation and invasion risk prediction, because of the trade‐offs among the CSR strategies.

功能策略在全球植物分布中的作用

了解物种分布的决定因素是生态学的中心主题。竞争，胁迫耐受性和定殖分别由格莱姆的竞争者（C），胁迫耐受性（S）和and葬（R）计划代表，它们是相互作用影响植物分布的三个重要功能。在这项研究中，我们汇编了2645种维管植物物种的数据集，以探索CSR策略在全球植物分布中的作用。我们使用系统发育广义最小二乘（PGLS）模型和系统发育路径分析方法，分析了CSR得分与物种范围大小之间的关联，这两者都说明了物种系统发生相关性，寿命和生长形式的影响。在不同的分布范围和增长形式上，功能策略范围大小的关联也有所不同。具体来说，物种的全球范围和本地范围的大小与R得分呈正相关；物种归化范围大小与C得分呈正相关；所有范围大小的测量值均与S得分负相关。这些模式主要是由草药驱动的，而不是由灌木或树木驱动的。对于物种的全球和本地分布，灌木的格局甚至与草药相反。我们的工作强调了区分不同分布范围和增长形式之间的功能策略-分布关联对于生态系统保护和入侵风险预测的重要性，因为企业社会责任策略之间需要权衡取舍。所有范围大小的测量值均与S得分负相关。这些模式主要是由草药驱动的，而不是由灌木或树木驱动的。对于物种的全球和本地分布，灌木的格局甚至与草药相反。我们的工作强调了区分不同分布范围和增长形式之间的功能策略-分布关联对于生态系统保护和入侵风险预测的重要性，因为企业社会责任策略之间需要权衡取舍。所有范围大小的测量值均与S得分负相关。这些模式主要是由草药驱动的，而不是由灌木或树木驱动的。对于物种的全球和本地分布，灌木的格局甚至与草药相反。我们的工作强调了区分不同分布范围和增长形式之间的功能策略-分布关联对于生态系统保护和入侵风险预测的重要性，因为企业社会责任策略之间需要权衡取舍。
