The global sharp decline of pollinators is one of the hot issues concerned by ecologists, mainly driven by global climate change, land use change, habitat fragmentation and harmful substances such as pesticides brought by industrial and agricultural production. In contrast, the potential impact of soil heavy metal pollution on pollinators is lack of in-depth evaluation. Heavy metals in soil would enter plant tissues, such as flowers, ., and be transmitted to pollinators during pollination. By affecting pollinators' behavior, they can change plant fitness for male and female. This review aimed to comprehensively sort out the status of research and existing problems, which would deepen our understanding on the ecological consequences caused by heavy metal pollution as well as the plant-animal relationship in response to environmental change. Summarizing previous researches, we reviewed findings on the pattern of heavy metal accumulation in flowers, the impacts of flower heavy metal accumulation on plant male and female fitnesses in addition to pollination behavior and the key aspects of life history of bees, to help understand the interrelationship between flower heavy metal accumulation and pollinators, and further expand the scientific understanding on the internal connection between soil heavy metal pollution and the decline of pollinators.
传粉者在全球范围内急剧减少，这是生态学家关注的热点问题之一，主要是由全球气候变化、土地利用变化、栖息地破碎化以及工农业生产带来的农药等有害物质所驱动。相比之下，土壤重金属污染对传粉者的潜在影响缺乏深入评估。土壤中的重金属会进入植物组织，如花朵等，并在授粉过程中传递给传粉者。通过影响传粉者的行为，它们可以改变植物的雌雄适合度。本综述旨在全面梳理研究现状和存在的问题，加深我们对重金属污染造成的生态后果以及植物与动物在应对环境变化时关系的理解。总结以往研究，我们回顾了花朵中重金属积累模式、花朵重金属积累对植物雌雄适合度以及授粉行为的影响，以及蜜蜂生活史的关键方面，以帮助理解花朵重金属积累与传粉者之间的相互关系，并进一步拓展对土壤重金属污染与传粉者减少之间内在联系的科学认识。
