Abstract:In order to make sure endangered medicinal plant resource in Jinfo Mountain, based on field investigation, specimen collection and identification for five years, the evaluation system of endangered medicinal plants in Jinfo Mountain was established including six indicators, e.g. deposit coefficient, endanger coefficient, genetic coefficient, valuable coefficient, conservation coefficient and breed coefficient. The results showed that 149 wild medicinal plants (including varieties and forms) in Jinfo Mountain suffered serious threat, belonging to 73 families and 113 genera. Seventy-four species needed to be key protected, such as Paris polyphylla, Euchresta japonica, Semiliquidambar cathayensis, Cibotium barometz, Gastrodia elata, Polygonatum sibiricum, Bletilla striata and so on. Sixty-five species needed to be took protective measures, e.g. Iris tectorum, Dioscorea zingiberensis, Cephalotaxus fortunei, Uncaria rhynchophylla, Cimicifuga foetida, Taxus wallichiana var. chinensis, Trichosanthes rosthornii, Penthorum chinense and so on. Ten species needed to be took general protective measures. According to priority protection value and resource utilization state, the proposal protection grades of 149 endangered medicinal plants in Jinfo Mountain were listed, in which 53 species to grade I, 48 species to grade II and 48 species to grade III.
