Global insect pollinator declines have prompted habitat restoration efforts, including pollinator-friendly gardening. Gardens can provide nectar and pollen for adult insects and offer reproductive resources, such as nesting sites and caterpillar host plants. We conducted a review and meta-analysis to examine how decisions made by gardeners on plant selection and garden maintenance influence pollinator survival, abundance, and diversity. We also considered characteristics of surrounding landscapes and the impacts of pollinator natural enemies. Our results indicated that pollinators responded positively to high plant species diversity, woody vegetation, garden size, and sun exposure and negatively to the separation of garden habitats from natural sites. Within-garden features more strongly influenced pollinators than surrounding landscape factors. Growing interest in gardening for pollinators highlights the need to better understand how gardens contribute to pollinator conservation and how some garden characteristics can enhance the attractiveness and usefulness of gardens to pollinators. Further studies examining pollinator reproduction, resource acquisition, and natural enemies in gardens and comparing gardens with other restoration efforts and to natural habitats are needed to increase the value of human-made habitats for pollinators.

种植花园以支持昆虫传粉者

全球昆虫传粉媒介的减少促使栖息地恢复工作，包括对传粉媒介友好的园艺。花园可以为成虫提供花蜜和花粉，并提供繁殖资源，例如筑巢地点和毛虫寄主植物。我们进行了一项审查和荟萃分析，以检查园丁在植物选择和花园维护方面所做的决定如何影响传粉媒介的生存、丰度和多样性。我们还考虑了周围景观的特征和传粉媒介天敌的影响。我们的结果表明，传粉媒介对高植物物种多样性、木本植被、花园大小和阳光照射做出积极反应，对花园栖息地与自然场所的分离产生消极反应。与周围景观因素相比，花园内特征对传粉媒介的影响更大。对传粉媒介园艺的兴趣日益浓厚，突出表明需要更好地了解花园如何促进传粉媒介保护，以及某些花园特征如何增强花园对传粉媒介的吸引力和实用性。需要进一步研究检查传粉媒介繁殖、资源获取和花园中的天敌，并将花园与其他修复工作和自然栖息地进行比较，以增加人工授粉栖息地的价值。
