摘要
在城市化导致的生物多样性丧失背景下,全球传粉昆虫面临严峻的生存危机。城市绿地因其多样化的生境及植物种类,对维持传粉昆虫生物多样性具有重要作用。蜜粉源植物作为传粉昆虫的主要食物资源,是传粉网络的重要组成部分。但目前对城市生态系统中传粉网络的结构还缺乏深入了解。本研究以城市绿地植物和传粉昆虫为基础构建定量的传粉网络,通过分析蜜粉源植物和传粉昆虫及其功能群组成、物种和网络层级上传粉网络结构特征,重点描述蜜粉源植物的来源、生活型、栽培状况、入侵性和园艺性5个特征,并探讨不同特征的蜜粉源植物对网络结构的影响。研究共记录到北京城市绿地中204种蜜粉源植物和141种传粉昆虫的814种4698次互作,成功识别出10种关键蜜粉源植物。蜜粉源植物的特征对传粉网络的结构具有显著影响,其中乡土植物、多年生草本或灌木、自生或低管理强度植物、非园艺种植物对网络的稳定作用更强。本研究证实了利用网络分析进行城市生物多样性保护科学决策的有效性,研究结果对优化蜜粉源植物的配置和管理,提升城市绿地的生态效益,促进城市生物多样性保护和可持续发展具有重要的理论和实践意义。
Under the background of biodiversity loss caused by urbanization,insect pollinators worldwide are facing severe survival crisis.Urban green spaces play an important role in maintaining pollinator biodiversity due to their diverse habitats and plant species.Nectar and pollen plants,which serve as the primary food source for pollinators,are essential components of the pollination network.However,there is currently a lack of in⁃depth understanding of the pollination network structure in urban ecosystems.We attempted to construct a quantitative pollination network in urban green spaces.We analyzed the nectar and pollen plants,pollinating insects and their functional group com⁃position,as well as the structure characteristics of the pollination network at the species and network levels.We de⁃scribed five characteristics of nectar and pollen plants:plant origin,life form,cultivation conditions,invasiveness,and horticultural traits.Additionally,the impacts of nectar and pollen plants with different characteristics on the network structure were also analyzed.We documented a total of 814 types of interactions between 204 nectar and pollen plant species and 141 pollinating insect species,with a total frequency of 4698 interactions.Ten key nectar and pollen plant species were successfully identified.The characteristics of nectar and pollen plants significantly af⁃fected the pollination network structure.Native plants,perennial herbs or shrubs,spontaneous plants or low⁃man⁃agement intensity plants,and non⁃horticultural plants played a stronger stabilizing role in the network.This study confirms the effectiveness of using network analysis to make scientific decisions for urban biodiversity conservation.Our findings had important theoretical and practical significance for optimizing the configuration and management of nectar and pollen plants,enhancing the ecological benefits of urban green spaces,and promoting urban biodiversity conservation and sustainable development.
