In cities, naturally regenerating plant populations are critical in sustaining both ecological function and ecosystem services. However, scientists have a limited understanding of the urban ecosystem conditions and stressors that influence basic life‐history processes and constraints for plant populations. Here, we synthesize current research on the recruitment dynamics of urban plants (processes associated with adding individuals to populations) and present a conceptual framework for urban recruitment limitation. From grasslands to forests, and from natural to constructed habitats, multiple urban drivers – including climate, land‐cover change, pollution, and biotic invasions – affect plant recruitment. These drivers often interact, and their effects are frequently species‐, habitat‐, or region‐specific. Furthering a “mechanistic” understanding (one that focuses on the underlying ecological mechanisms of observed phenomena) of how these drivers alter plant population dynamics will improve the conservation, management, and restoration of urban greenspaces.

城市中的植物：了解城市景观中的招聘动态

在城市中，自然再生的植物种群对于维持生态功能和生态系统服务至关重要。但是，科学家对城市生态系统条件和影响基本生命史过程和植物种群限制因素的压力因子的了解有限。在这里，我们综合了关于城市植物招聘动态（与将个人添加到人口相关的过程）的最新研究，并提出了城市招聘限制的概念框架。从草原到森林，从自然到人工栖息地，包括气候，土地覆盖变化，污染和生物入侵在内的多种城市驱动因素都会影响植物的吸收。这些驱动因素经常相互作用，其影响通常是特定物种，栖息地或区域的。
