| Abstract: |
| Primulina yangshuoensis is a perennial herb of Gesneriaceae which specially grows in karst rock
areas of Yangshuo county，has high ornamental and medicinal value. In order to understand the status of its wild
population，we carried out a survey on geographical distribution，ecological environment，population structure and
renewal，community characteristics of P. yangshuoensis from march 2013 to April 2017，The results showed that
there was only one population in the wild，and the number of individuals was very small，the species was getting
critically endangered. One of the most important reasons for the endangerment of P. yangshuoensis was the longterm
mining and destruction of natural ecological environment by human，the second reason was that the special
biological characteristics of the species itself inhibited the development of the population. According to the current
survival status of the species，the article suggested that following protection strategies: legislative protection and in
situ conservation，propaganda of the conservation and science education about the wild plant，ex situ conservation
and study on propagation technology，reintroduction and reestablishment of the species populations. |
