广西稀有濒危植物迁地保护评价

从迁地保护的内容、适应性、有效性等方面对桂林植物园迁地保护稀有濒危植物进行评价,结果表明:迁地保护的稀有濒危植物科学性强,96%以上的物种有科学记录,除了银杏等少数几个种属于“保护性收集”外,其它都是“具有保护意义的收集”;75%的种适应或基本适应迁移地的环境,原分布于广西的种明显比分布于广西区外的种适应性更强。按照最小存活种群的标准,该园有73种稀有濒危植物迁地保护有效。

An evaluation on the rare and endangered plants under ex-situ conservation in Guangxi

According to the ex-situ conservation means,adaptation,effectiveness etc,the rare and endangered plants under ex-situ conservation in Guilin Botanical Garden are evaluated. The results show that there’s high scientific quality of these plants,more than 96% of the species have been recorded scientifically,75% of them are adapted or constrainedly adapted to habitat of ex-situ area. A few species belong to“conservation collection”including Ginkgo biloba,others are all“collection with conservation value”. Otherwise,species endemic to Guangxi have stronger adaptability than those beyond Guangxi significantly. According to standard of minimum viable population,the ex-situ conservation of 73 rare and endangered plants are effective.
