中国苦苣苔科植物濒危现状与多样性保护

中文摘要英文摘要

截至2021 年12 月31 日,我国已知苦苣苔科植物共有??805 种(含种下等级,下同),隶属于??45 个属,主要分布在西南至华南地区,其中特有种和狭域种十分丰富。苦苣苔科大部分种类仅适应于某些特化的微生境,因此极易由于自身的原因和外界因素的干扰而致危。为了更好地了解我国苦苣苔科已知物种的濒危风险,在查阅相关文献并结合参考最近发表的新分类群中关于濒危等级评估相关内容的基础上,辅以近年来实地调查掌握的第一手资料,我们对中国苦苣苔科已知物种的濒危等级进行了统计分析和重新评估。同时,依托中国野生植物保护协会苦苣苔专业委员会、广西植物研究所国家苦苣苔科种质资源库和中国苦苣苔科植物保育中心平台,首次创新了从新种发现和发表、濒危状况评估、即时启动保育和园艺新品种培育同步进行的物种保护新模式。分析结果表明,有必要提高政府相关部门对苦苣苔科植物多样性保护的重视程度。因此,建议:(1)进一步加强对中国苦苣苔科植物种质资源保护紧迫性的认识;(2)针对濒危的,尤其是被评估为极危(CR)和濒危(EN)的类群开展??“抢救性保护”、迁地与就地保护和野外回归;(3)积极开展新品种培育等方面的研究。这些是将来苦苣苔科植物多样性保护的重要基础和必要前提。

here are a lot of endemic and narrowly distributed species in the family, Gesneriaceae, in Chinas higher plants, 805 known species (including infraspecies, same as followings), belong to 45 genera, before December 31st, 2021, and mainly found from Southwest toward South China. Apart from a few species, most species in China are specifically tuned to the certain micro-habitats so that they are easily influenced becoming endangered status by the own factors and external factors. For better understanding the endangered risks of known species of Gesneriaceae in China, we re-assessed the IUCN red list categories of Chinas Gesneriaceae taxa, and then calculated and analyzed the databased on consulting relevant literature and collecting the endangered data of new reported taxa in recent years, and coupling with detailed field investigations for Gesneriaceae in China. At the same time, relied on Gesneriad Committee of China Wild Plant Conservation Association, National Gesneriaceae Germplasm Resources Bank of GXIB and Gesneriad Conservation Center of China, we first created and formulated a new mode, which execute simultaneously new taxa discoveries and formal publications, assessments of the taxons endangered status, immediately launching conservation programs and new horticultural variety cultivations. Analysis results demonstrate that it is necessary to enhance the attention degree of protection of Gesneriaceae biodiversity by relevant government departments. Thus, we suggest: (1) To further strengthen the understanding for the urgency of protection of China's Gesneriaceae germplasm resource; (2) To conduct series of researches about rescuing conservation, ex & in-situ conservation, re-introduction in similar habitats and development for those groups in CR & EN categories; (3) To promote the development of breeding of new horticultural varieties of Gesneriaceae. All are the important base and essential precondition of Gesneriaceae biodiversity conservation.
