摘要:

启动实施以国家公园和国家植物园体系为主导的就地和迁地保护相结合的生物多样性保护大战略, 是我国作为世界生物多样性大国之一的科学使命和责任担当。本文以国家重点保护、受威胁和中国特有维管植物为对象, 系统梳理了这3类植物在我国植物园的迁地保护概况, 对这些植物的生活型、物种组成和系统发育多样性进行了比较分析, 以期为当下国家植物园体系建设提供科学参考和依据。结果表明, 我国植物园保存的此3类植物共计7,141种, 分属265科1,271属, 分别占我国维管植物科、属、种总数的76%、42%和23%。在7,141种植物中, 国家重点保护植物743种, 受威胁植物2,095种, 中国特有植物5,957种, 分别占我国国家重点保护、受威胁和特有植物总数的72%、59%和37%。这些植物包括乔木2,555种、灌木1,025种、草本3,117种、攀缘类419种和水生类25种。3类植物在各植物园的物种组成共有比例较低, 系统发育多样性存在显著差异。

Abstract

Background & Aims: As one of the mega-biodiverse countries in the world, China has implemented in situ and ex situ biodiversity conservation programs through the national parks and the national botanic gardens system respectively to responsibly study and conserve this diversity. We aimed to provide a baseline reference for the current national botanic garden system program.

Methods: We assessed the ex situ conservation profile in Chinese botanic gardens of plants from three categories: National Key Protected Wild Plants (NKPWP), threatened species, and endemic species. Statistical and comparative analyses of integrated data sets show that there are 7,141 species of vascular plants that have been conserved ex situ in botanic gardens of China. These species span 1,271 genera and 265 families, accounting for 76% of families, 42% of genera, and 23% of species of vascular plants in China.

Results: Among the 7,141 species, 743 species are National Key Protected Wild Plants, 2,095 species are threatened, and 5,957 species are endemic to China, accounting for 72%, 59% and 37% of the total number of species catalogued for these categories in China, respectively. These species include 2,555 trees, 1,025 shrubs, 3,117 herbs, 419 climbers, and 25 aquatic plants. The phylogenetic diversity is variable among these gardens, with a low proportion of shared species across gardens.
