Study of Present Situation of Mild Coptis Omeiensis Resources and Protection Approach

As an endangered medicinal plant of Chinese traditional medicine,Coptis omeiensis attracts extensive attention due to its long-history of medicinal use,small distribution region,and gradual decrease of the wild population in recent decades.According to the distribution record of this plant and investigation of planting regions,more than 30 sites were elected and investigated.There are 20 distribution sites for wild populations around Emei city,Yahong county,Ebian county,Yingjing county of Meishan.The investigation results show that there are no more than 360 ha for the distribution of wild resource population of Coptisomeiensis,and about 2 000 kg(dry matter of root) in total can be used for medicinal purpose.It is estimated the annual maximum permitted harvest mass should be 200 kg(dry matter of root) for sustainable existence of the wild population.The main problems of the wild plants are the followings:because of the special growth environment,it is difficult for them to propagate naturally,the habitat area is decreasing and falls to pieces and their protections are not enough.It is suggested that protection sites be set up for the wild population,introduction of variety as well as domestication and the development of the resources be strengthened to realize man-made planting,which are an essential way for protecting the wild Coptis omeiensis.
