【摘要】 珍稀濒危植物的保护是生物多样性保护的一个重要内容。本文通过在鼎湖山国家级自然保护区的实例研究,论述了珍稀濒危植物就地保护和迁地保护的原理以及它们结合的优越性。鼎湖山既是一个自然保护区,又是一个树木园,其野生珍稀濒危植物种群数量14年来基本保持稳定,多数略有增长。在保护条件下,珍稀濒危植物能保持较稳定的种群水平,但一些珍稀植物因为生物学原因在原生环境里也无法生存,只有创造更加适合其生存与发展的新环境,这就是迁地保护。一些珍稀濒危物种在绝对保护条件下,因环境向不利于其生存发展的方向变化,这也需要迁地保护或采取干扰环境的方法。研究和实践证明,就地保护是珍稀濒危植物保护的最佳方法,但仅有就地保护还不够,尚需迁地保护作补充。迁地保护和就地保护各有优劣之处,只有二者结合,才能使珍稀濒危植物的保护更加有效。
【Abstract】 Protecting rare and endangered plants is an important part of biodiversity conservation. This paper explored the availability and advantages about the combination of in situ conservation and ex situ conservation, based on a case study made in Dinghushan Biosphere Reserve, which is also an arboretum. From 1983 to 1997 in Dinghushan, the populations of rare and endangered plant species have been stable and some have increased, but some have decreased because they can not survive in their primitive habitats. Under strict protection, as the community succession occurred, the micro-habitats changed and is no longer suitable for some species’growth. The measure to solve this problem is to interfere the habitat succession and keep its original state. Another solution is ex situ conservation--moving the rare and endangered plants to the man-made habitats in botanical gardens. To check if the ex situ conservation succeed or not, the best way is to reintroduce these rare and endangered plants to nature reserves. We believe that, combination of in situ and ex situ conservation is effective for the conservation of rare and endangered plants.
