摘要: 灌木作为干旱半干旱地区植被的主要组成部分,对于维持生态系统稳定性和发挥生态服务功能具有重要作用。灌丛保育效应可以减轻限制性因子对目标植物生长和繁殖的不利影响,促进退化生境植物物种自然更新和植被恢复。本文综述了近20年有关灌丛保育效应研究和应用的主要成果,从微生境改善、肥岛形成、防御和抵抗作用发挥、有益微生物引入和协助繁殖体传播或保存以及种间竞争网络格局改变等方面阐述灌丛保育效应的促进机制,并从非生物环境、生物干扰、生活史阶段和生长繁殖策略等方面分析影响灌丛保育效应发挥的关键因素。从完善灌丛保育效应的理论机制和开展多因素共同作用下多植物物种相互作用关系模型构建角度,对灌丛保育效应的研究进行了展望。

Abstract: Shrubs are the major components of vegetation in arid and semi-arid areas, and play a pivotal role in maintaining ecosystem stability and function. The nurse effects of shrubs can help with the regeneration of native target plant species by alleviating the adverse influences that limit their growth and reproduction in degraded habitats. We summarized the main research results and application of shrub nurse effects in the last 20 years. We discussed several facilitation mechanisms of nurse shrubs, including microhabitat amelioration, fertile island formation, defense and resistance against herbivores, introduction of beneficial microorganism and propagule propagation or preservation, as well as changes in the patterns of interspecific competitive networks. Key factors affecting nurse effects were analyzed, including abiotic environments, biological disturbances, plant life history as well as growth and reproductive strategies. Prospects for future research were also considered from the aspects of improving theore-tical mechanisms of nurse effects by shrubs and building models involved in multiple plant species interaction affec-ted by multifactors.
