【摘要】 猫爪藤(Dolichandra unguis-cati)是一种原产于热带美洲的外来入侵藤本植物，最初作为观赏植物引入栽培，但随着生长区域的扩大，其对城市生态景观和物种多样性危害严重。近年来，随着经济全球化和气候变化，猫爪藤在南方，特别是一些主要沿海城市呈现较严重的入侵态势，如不加以防范，可能发展成为危害严重的入侵物种。目前，国内关于猫爪藤的相关研究甚少，对其特性了解不多。在搜集国内外相关研究文献的基础上，从繁殖策略、生长策略和竞争策略等3个方面归纳分析猫爪藤的主要研究现状。结果表明：块茎繁殖策略、运动习性、多胚现象、低叶片建成成本和凋落物遗留效应，这些特征或特性是猫爪藤入侵性的主要原由。通过研究分析，旨在揭示猫爪藤入侵性的源由和一般特点，阐明防除技术和利用价值，同时探寻研究空白点，以期为进一步深入研究猫爪藤入侵特性提供参考，为做好预警、防除和价值利用等工作提供科学依据。更多还原

【Abstract】 Dolichandra unguis-cati is an invasive alien vine native to tropical America.It was first introduced into cultivation as an ornamental plant, and then, with the expansion of growing areas, it has seriously harmed the urban ecological landscape and species diversity.In recent years, with the economic globalization and climate change, D.unguis-cati has shown a serious invasion in the south, especially in some major coastal cities.If not prevented, it may develop into a serious invasive species.At present, there is little research on D.unguis-cati in China, and little understanding of its characteristics.On the basis of collecting relevant literatures at home and abroad, this paper summarized and analyzed the main research status of D.unguis-cati from three aspects: reproductive strategy, growth strategy and competition strategy.The results showed that tuber propagation strategy, motility, polyembryology, low leaf building cost and litter legacy effect were the main causes of the invasion.Through research and analysis, the purpose is to reveal the origin and general characteristics of the invasiveness of D.unguis-cati,and clarify the control technology and utilization value.At the same time, this paper explored the research blank points, in order to provide a reference for further in-depth study of the invasion characteristics of D.unguis-cati,to provide a scientific basis for early warning, control and value utilization.更多还原
