入侵植物对气候变化响应的研究新进展

Recent Progress in the Responses of Invasive Plants to Climate Change

  • 摘要: 全球气候变化导致外来植物入侵问题愈发严重,对生物多样性和生态系统稳定性造成严重威胁。依据2012—2022年间Web of Science数据库中生态学领域国际权威期刊发表的关于入侵植物对气候变化响应的SCI论文,对该领域的最新研究动态进行了分析,为入侵植物防治及入侵态势预测提供参考。研究发现: 全球气候变暖显著提升了入侵植物的物候可塑性、种间竞争力、生长-防御权衡策略及沿纬度梯度的扩散速率,而降雨量上升、干旱和大气二氧化碳浓度上升对植物入侵进程的影响则存在多变性;全球化背景下多因子交互作用导致入侵生态系统的响应更为复杂。该领域未来研究重点包括: (1)生物、非生物因子对入侵植物的综合效应;(2)本土、入侵植物对于多类资源脉冲的异质性响应;(3)气候变化下入侵生态系统的多营养级互作关系;(4)采用原位群落移栽的手段探讨入侵植物的气候适应性。

     

    Abstract: Global climate change leds to the increasingly serious alien plant invasion, which causes serious threat to biodiversity and ecosystem stability. Based on the SCI articles about the responses of invasive plants to climate change that published on international authoritative ecological journals in the web of science database from 2012 to 2022, the recent research trends on this field are analyzed, for providing reference for bio-control of invasive plants and predicting their invasion situations. It is found that global warming significantly improved the phenological plasticity, interspecific competitiveness, growth defense trade-off strategy and diffusion rate of invasive plants along latitudinal gradient, while the impacts of rising rainfall, drought and rising atmospheric carbon dioxide concentration on this process are variable. Under global change, the interaction of multiple factors would lead to the more complex responses of invasive ecosystems. Future research priorities include: (1) Comprehensive impacts of biotic and abiotic factors on invasive plants. (2) Heterogeneous responses of native and invasive plants to multiple resource pulses.(3) Multi-trophic interactions of invasive ecosystems under climate change. (4) Examining the climatic adaptability of invasive plants by using the situ community transplantation.
