The relationship between plant invasions and global change is complex. Whereas some components of global change, such as rising CO2, usually promote invasion, other components, such as changing temperature and precipitation, can help or hinder plant invasion. Additionally, experimental studies and models suggest that invasive plants often respond unpredictably to multiple components of global change acting in concert. Such variability adds uncertainty to existing risk assessments and other predictive tools. Here, we review current knowledge about relationships between plant invasion and global change, and highlight research needed to improve forecasts of invasion risk. Managers should be prepared for both expansion and contraction of invasive plants due to global change, leading to increased risk or unprecedented opportunities for restoration.
植物入侵与全球变化之间的关系是复杂的。虽然全球变化的某些组成部分，如二氧化碳浓度上升，通常会促进入侵，但其他组成部分，如温度和降水的变化，可能有助于或阻碍植物入侵。此外，实验研究和模型表明，入侵植物通常对协同作用的多个全球变化因素表现出不可预测的反应。这种可变性增加了对现有风险评估和其他预测工具的不确定性。在这里，我们回顾了植物入侵与全球变化之间关系的现有知识，并强调了提高入侵风险预测所需的研究。由于全球变化，管理者应该为入侵植物的扩张和收缩做好准备，这将导致风险增加或恢复的前所未有的机会。
