Urbanization has rapidly increased in recent decades and the negative effects on biodiversity have been widely reported. Urban green areas can contribute to improving human well-being, maintaining biodiversity, and ecosystem services (e.g. pollination). Here we examine the evolution of studies on plant–pollinator interactions in urban ecosystems worldwide, reviewing also research funding and policy actions. We documented a significant increase in the scientific production on the theme in recent years, especially in the temperate region; tropical urban ecosystems are still neglected. Plant–pollinator interactions are threatened by urbanization in complex ways, depending on the studied group (plant or pollinator [generalist or specialist]) and landscape characteristics. Several research opportunities emerge from our review. Research funding and policy actions to pollination/pollinator in urban ecosystems are still scarce and concentrated in developed countries/temperate regions. To make urban green spaces contribute to the maintenance of biodiversity and the provision of ecosystem services, transdisciplinary approaches (ecological–social–economic–cultural) are needed.

近几十年来，城市化迅速发展，对生物多样性的负面影响已被广泛报道。城市绿地有助于改善人类福祉、维护生物多样性和生态系统服务（例如授粉）。在这里，我们研究了全球城市生态系统中植物-传粉媒介相互作用研究的演变，同时回顾了研究资金和政策行动。我们记录了近年来有关该主题的科学生产显着增加，尤其是在温带地区；热带城市生态系统仍然被忽视。植物与传粉媒介的相互作用受到城市化的复杂威胁，具体取决于所研究的群体（植物或传粉媒介[通才或专家]）和景观特征。我们的评论出现了几个研究机会。城市生态系统中授粉/授粉媒介的研究资金和政策行动仍然稀缺，并且集中在发达国家/温带地区。为了使城市绿地有助于维护生物多样性和提供生态系统服务，需要跨学科方法（生态-社会-经济-文化）。
