摘要归化植物在当地植物多样性和生态功能中发挥着重要作用，然而，人们对归化的驱动因素仍知之甚少。因此，了解外来植物在当地自然栖息地的发展和优势的过程是至关重要的。本研究首次从群落结构和种群动态两个方面详细报道了中国引种的长圆花Cydonia oblonga。我们进行了全面的调查，通过现场社区调查，访谈和文献综述的物种。Cydonia oblonga是一种古老的果树，在世界范围内有4500多年的引种历史，在我国有2500多年的栽培历史。我们分析了C.利用时空替代法对长圆花群落结构进行了研究，并利用静态生命表、存活曲线和时间序列模型对种群动态进行了定量分析，探讨了长圆花的自然化过程。获得了以下结果。(i)群落由20科28属31种维管植物组成，其中木本16种，草本15种。蔷薇科和菊科是两个最具优势的科。(ii)灌木层中的所有个体以及C. oblonga种群的基部直径分布大致呈倒J形。观察到完整的年龄结构，生存曲线被归类为Deevey II型。根据时间序列分析，估计未来种群数量将增加，特别是中型和大型个体。(iii)宗教交流、强大的资源竞争力以及与原产地的相似性可能是引种和成功归化的主要驱动力。长方形。这些结果表明，与本地物种密切相关的外来物种更有可能入侵，归化，并在当地栖息地的社区占主导地位。
Abstract Naturalized plants play pivotal roles in local plant biodiversity and ecological functions; however, the drivers of naturalization remain poorly understood at a fine scale. Thus, understanding the processes of the development and dominance of alien plants in local natural habitats is of paramount importance. In the present study, we report for the first time the naturalization of Cydonia oblonga in China based on community structure and population dynamics at a fine scale. We conducted a comprehensive survey of the species through field community investigations, interviews, and a literature review. Cydonia oblonga is an ancient fruit tree with a long introduction history of over 4500 years worldwide and a cultivation history of over 2500 years in China. We analyzed C. oblonga community structure using the spatiotemporal substitution method and quantitatively analyzed population dynamics using a static life table, survivorship curve, and time series model to explore the naturalization processes. The following results were obtained. (i) The community comprised 31 coexisting vascular plant species (16 woody and 15 herbaceous species) belonging to 28 genera in 20 families. Rosaceae and Asteraceae were the two most dominant families. (ii) All individuals in the shrub layer as well as the C. oblonga population exhibited a roughly inverted J‐shaped basal diameter distribution. A complete age structure was noted, and the survival curve was classified as Deevey type II. According to time series analysis, the population is estimated to increase in the future, specifically of medium and large individuals. (iii) Religious exchange, potent resource competitiveness, and similarity with the native habitat may be the major drivers of the introduction and successful naturalization of C. oblonga. These results suggest that alien species closely related to native ones are more likely to invade, naturalize, and dominate communities in local habitats.
