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.
