关于植物迁地保护若干问题的讨论

Discussion on the plant ex situ conservation

植物迁地保护将是正在建设的国家植物园体系的核心任务,然而,有关植物迁地保护在植物多样性保护中的地位与作用、我国植物迁地保护的目标应该如何确立等诸多问题尚待讨论。本文通过文献研究,简要回顾了植物迁地保护的发展历史、过去40年国内外植物迁地保护取得的成绩,澄清了人们对植物迁地保护工作的一些疑虑;结合《昆明-蒙特利尔全球生物多样性框架》和即将发布的《支持<昆明-蒙特利尔全球生物多样性框架>实施的植物保护相关的自愿补充行动》,提出我国植物迁地保护的目标应该为“对所有受威胁植物实施有效的迁地保护,包括保护其遗传的多样性和代表性”。

Aims:Plant ex situ conservation will be a core task in the on-going construction of the national botanical garden system of China.However,many issues regarding the status and role of plant ex situ conservation in biodiversity conservation,as well as how to set up the goals for plant ex situ conservation in China,are still under discussion.The objective of this study is to address these unresolved issues.Methods:The study utilizes literature reviews and international conventions such as the“Kunming-Montreal Global Biodiversity Framework”and the upcoming“Complementary Actions Related to Plant Conservation to Support the Implementation of the Kunming-Montreal Global Biodiversity Framework”.Results:Through a review of the development history and achievements of plant ex situ conservation over the past 40 years,this paper clarifies some doubts and misconceptions about plant ex situ conservation.Furthermore,this article proposes the goals of plant ex situ conservation in China,as“Establish programs to ensure ALL threatened plant species are effectively conserved by ex situ methodologies,aiming to achieve genetically diverse representations”.Conclusion:The establishment of the national botanical garden system in China presents an opportunity to enhance plant ex situ conservation efforts.By improving the quality of processes involved in ex situ conservation program,China can elevate its conservation practices to a higher level.
