| 摘 要： | 瑶山苣苔(Dayaoshania cotinifolia W.T.Wang)是苦苣苔科多年生草本植物,为国家Ⅰ级重点保护野生植物.在2004-2006年对瑶山苣苔资源现状、生物学和生态学特性调查的基础上,探讨了瑶山苣苔的濒危原因及解濒措施.结果表明,人为原因是导致瑶山苣苔濒危的最主要原因;其次是昆虫对瑶山苣果实的捕食显著减少了种子数量;第三,瑶山苣苔同有的生物学特性限制其种群数量增加.为更好的保护瑶山苣苔,作者建议采用就地保护策略,即建立金秀老山自然保护区独木桥和青年工区两个瑶山苣苔保护点,有效地保护该种群及其分布生境;同时加强瑶山苣苔的科学研究,实施迁地保护. |

| Abstract: | Dayaoshania cotinifolia W. T. Wang is perennial of the Gesneriaceae. Because of limited population size and significant scientific research value,it is listed in the first class key protected wild plants of China as well as in China Species Red List. Basing on field investigation on habit quantity,biological and ecological characteristics of D. cotinifolia from 2004 to 2006,the causes of endangerment were examined and methods of changing the endangered status and refraining from extinct were proposed as wel... |
