摘　　要：为弄清济宁市外来入侵植物的区系成分及多样性成因,减少外来入侵植物对济宁市生物多样性的影响提供理论依据。在已知济宁市外来入侵植物种类组成的基础上,通过实地调查对其科、属、种的分布区类型进行了分析,探讨了外来入侵植物多样性的成因。结果表明:在区系组成上,济宁市外来入侵植物的热带性成分占绝对优势,其比例在科、属、种水平上分别为83.33%、52.55%和53.61%。入侵种所在科、属,常广域分布,但入侵种原产地分布范围却不大,并倾向于集中在某些特定区域(如美洲、狭义地中海区)。The aim of the present study was to understand the floristic and diverse causes of invasive alien plants in Jining City,and to provide a theoretical basis for reducing the impact of invasive alien plants on biodiversity in Jining City.Based on the list of invasive alien plants in Jining City,a floristic analysis of their families,genera,and species was conducted.Tropical components were predominant in the floristic composition of invasive alien plants in Jining City,with the proportions of 83.33%,52.55% and 53.61% at family,genus,and species levels,respectively.The distribution of the families and genera of invasive alien species often varies,but most species are narrowly distributed and tend to be concentrated in specific regions(such as America and the Mediterranean region)
