江西省伞形科植物区系地理与多样性研究

Flora Geography and Diversity of Apiaceae Plants in Jiangxi Province

[目的]研究江西省伞形科植物区系地理特征与多样性特点,为江西省伞形科植物资源的保护和合理开发利用提供理论依据。[方法]采用野外调查和文献资料查询相结合的方法,对江西省伞形科植物的区系地理成分、物种多样性和功能多样性等进行了研究。[结果]江西省伞形科植物属的区系地理成分复杂多样,区系起源古老,具有明显的温带性质,无江西省特有植物。江西省伞形科植物种类组成比较丰富,有26属60种(含变种);优势属明显,少种属和单种属占总属数的比例分别为53.85%和46.15%。[结论]江西省伞形科植物区系地理成分多样,植物组成丰富,功能多样,建议加强江西省伞形科植物资源的保护、评价、引种驯化和开发利用。

[Objective] To research the flora geography and diversity of Apiaceae plants in Jiangxi Province,and to provide theoretical foundation for the resources protection and rational development of Apiaceae plants in Jiangxi Province. [Method]Using the method of field investigation and data query,we researched the flora geography,species diversity and function diversity of Apiaceae plant in Jiangxi Province.[Result]The floristic geographical elements of genera of Apiaceae plants were complex,diverse,and showed obvious temperate zone characteristics. The floristic origin of Apiaceae plants was very ancient,with no endemic plants in Jiangxi Province. There were abundant Apiaceae plants in Jiangxi Province with 60 species（ including varieties） and 26 genera in general. The dominant genera were prominent,and the percentage of minor genus and single genus reached 53. 85% and 46. 15% of total number of genera,respectively. [Conclusion] Apiaceae plant in Jiangxi Province has various functions,many geographical elements of flora and abundant plant components. It is suggested that we should strengthen the protection,evaluation,introduction,acclimatization,development and utilization of Apiaceae plants in Jiangxi Province.
