Wulingshan region is located on the border between Hunan,Hubei,Chongqing,Guizhou. In the area,the geographical composition is complicated,the climate is warm and humid,ecological environment is complicated,gestates rich biological resources,but there are also many endangered plants in urgent need of research and conservation. This paper reviewed researches on the survey of the endangered plants resource,the genetic diversity research,conservation and use of it in Wulingshan region. It can provide scientific reference for the protection and sustainable development of these endangered plants,and play an active role in protection of biological diversity in Wulingshan region.
