Abstract:
The unique rare aquatic Ottelia acuminata is listed the third class national endangered plant in China.In this study,the cause of being in imminent danger for Ottelia acuminata was discussed by the way of combining the investigation on Ottelia acuminata resources,biological and ecological characteristics with the observation of its cultivars over 20 years,and the conservation strategies of Ottelia acuminata were thus proposed.Both natural factors and human factors were revealed in this study.The results showed that such factors as the limitation of inherent biological characteristics to its population quantity,human interference,water eutrophication,algae restraint,nibbling of aquatic animals and human excessive dredging might become the significant reasons causing endangered Ottelia acuminata.It was proposed in this study that some effective conservation strategies of Ottelia acuminata should be taken by protecting its water resources in original residence,its growth environment and populations so as to realize insitu conservation,besides,some exsitu conservation strategies of Ottelia acuminata as introduction and domestication and scientific research should also be taken to increase its population of Ottelia acuminata.
