金佛山濒危药用植物资源及其评价体系的建立

Resource Investigation and Evaluation System Establishment of Endangered Medicinal Plants in Jinfo Mountain

摘要:

为弄清金佛山的濒危野生药用植物资源,经过5年的野外调查、标本采集与鉴定,建立了以蕴藏系数、濒危系数、遗传价值系数等6项指标在内的金佛山濒危药用植物评价体系。结果表明,金佛山有73科113属149种野生药用植物(含变种、变型)的生存受到较为严重的威胁,其中急需重点保护的物种有74种,需要采取保护措施的有65种,需要采取一般保护措施的有10种。根据各物种的优先保护值和资源利用情况,列出了149种濒危药用植物的建议保护等级,其中建议列为Ⅰ级保护的53种,列为Ⅱ、Ⅲ级保护的各48种。

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.
