摘要
兰科植物是植物保育中的“旗舰”类群 (flaggroup)。中国不是兰科植物种类最丰富的地区 ,但具有最复杂多样的地理分布类型以及众多的原始类群 ,因此 ,开展对中国兰科植物的研究和保育是世界兰科植物研究和保育工作中的重要组成部分。本文介绍了目前中国兰科植物研究和保育的现状 ,分析了与国际同类工作相比存在的差距 。
Orchids are a flagship group in plant conservation. There are about 1,247 species and about 171 genera in China. The Chinese orchid flora is distinguished by having rich diversity in geographical types, especially by having a broad subtropical area lying between the Qinling Mountains and the Tropic of Cancer. This paper generally reviews the present situation of research and conservation of Chinese orchids. The publication of three volumes of flora of China (Orchidaceae), and some local flora of orchids, such as those for Hainan, Yunnan, Sichuan, and Guangxi Provinces, has laid down a profound foundation not only for correctly identifying and naming Chinese orchids but also for properly making conservation policy and strategies. Compared with relatively rich taxonomic knowledge, however, there is a wide gap in our knowledge of orchid ecology and many other aspects of orchid biology related to conservation. Five main priorities for education and scientific research for the long and short terms are suggested. First, strengthen and improve basic research such as ecology, biology and floristics. Second, identify and categorize Chinese orchid diversity hot spots at the country level. Third, promote study of ex situ conservation techniques, particularly developing artificial propagation methods for commercially important species, and starting reintroduction of selected endangered species. Fourth, develop public education programs through school lessons, the press, TV and radio. Finally, establish a scientific information pool at national level.
