Current situation of wild resources of Nervilia fordii in Guangxi
By field investigation combining with interview investigation,the distribution of wild resource in Guangxi,species of medicinal materials,community characteristic and resource reservation etc. of Nervilia fordii were investigated. The results showed that:N.fordii distributed mainly in limestone mountainous region in Guangxi,it could be divided into two kinds(large leaves and small leaves)according to commercial specification. The small-leaves one(N.fordii)was investigated in this paper,and the large-leaves one(N.plicata),which belonged to the same genera with N.fordii,was sold and used as N.fordii;the community structure of N.fordii was appreciably different in different producing areas;wild resource distribution area of N.fordii was becoming more and more limited and its wild resource quantity had reduced rapidly,because of the excess collection by human and the change of ecological environment. According to the investigation,wild resource reservation of N.fordii was only 4 815 kg,various active measures should be adopted to protect wild resource of N.fordii in order to ensure the sustainable utilization of it.
