摘要
兰科植物是被子植物中种类最多的大科之一,也是植物保护中的旗舰类群。兰科植物的多样性更多被认为是适应于多样化的特化传粉者的结果,但目前大多数措施仍只对兰科植物本身或其栖息地进行保护,而很少考虑其传粉系统。实际上,兰科植物既是资源限制物种,也是传粉者限制类群。兰科植物与其传粉昆虫之间是一种极不对称的关系,兰花对其传粉昆虫的依赖远远大于传粉昆虫对兰花的依赖。因此在对兰花本身采取保护措施的同时,要重视对兰花-传粉者这一传粉系统进行保护。
The Orchidaceae are among the most species-rich plant families and are renowned as the flagship family in plant conservation. The great taxonomic diversity of the Orchidaceae is often attributed to adaptive radiation for specific pollinators. However, there are many gaps in our knowledge of orchids, particularly in fully understanding the orchid-pollinator relationships. In fact, orchids were primarily pollination limited as well as resource constraints. The relationship between orchids and their pollinators was asymmetric, with the orchids depend more on pollinators than the reverse. Therefore, we should also not forget to preserve the orchid＇s pollination systems.
