南雄丹霞梧桐自然保护区药用植物资源多样性研究

Diversity Research of Medicinal Plant Resources in theFirmiana danxiaensis Nature Reserve in Nanxiong City

为全面摸清广东省南雄市丹霞梧桐自然保护区内药用植物种类,填补当地药用植物资源方面的漏缺,对保护区内的野生药用植物进行实地调查、文献查阅、专家咨询及相关内容分析。根据调查统计,保护区内现有野生药用植物159科453属704种,其中蕨类植物27科39属66种,裸子植物6科6属6种,被子植物126科408属632种。从药用植物资源的科属、入药部位、药性、药味等4个方面和珍稀保护植物种多样性进行了统计分析,并总结归纳了药用植物的多样性特征,为野生药用植物的开发利用和可持续发展提供有力的科学依据。

In order to fully understand the species of medicinal plants and fill the gaps in local medicinal plant resources of the Firmiana danxiaensis Nature Reserve in Nanxiong City,we conducted field investigation,literature review,expert consultation and relevant content analysis on wild medicinal plants in the reserve.According to the investigation and statistics,there were 704 species of wild medicinal plants in 159 families 453 genera in the Nature Reserve,including 66 species of ferns in 27 families 39 genera,6 species of gymnosperms in 6 families 6 genera,632 species of angiosperms in 126 families 408 genera.Statistical and diversity analysis was carried out from the four aspects including families and genera,medicinal parts,nature of the medicine and medicinal taste,and the diversity of rare and protected plant species,and summarized the diversity characteristics of medicinal plants,which provided a strong scientific basis for the utilization of medicinal plant species and the sustainable development of the wild medicinal plants.
