摘    要:以景东无量山国家级自然保护区为对象,通过样地调查、标本鉴定和查阅资料,对保护区内药用维管植物的种类和生存状况进行研究。结果显示,保护区内药用维管植物共有80科168属218种,占该区维管植物总数的57.37%。药用维管植物生长型分析表明,草本植物占绝对优势。药用部位分析表明,以根和全草入药是其主要利用形式。对药用维管植物的功效分析显示,该地区以清热类、活血化淤类和祛风湿类药物为主。对保护区内药用维管植物濒危等级的评估显示,无危种类占总数的82.11%,说明保护状况良好。保护区不同功能区内维管植物物种丰富度为:核心区缓冲区实验区,其中药用维管植物所占的比例为:核心区缓冲区实验区。对不同功能区药用维管植物相似性分析结果表明,核心区和实验区物种为极不相似;核心区和缓冲区物种为轻度相似。本研究表明保护区的建立对药用植物多样性保护起到了重要作用,明确了保护区药用维管植物的种类及生存状况,为进一步开展药用植物资源的保护和利用研究提供了参考。

关 键 词:药用维管植物资源  物种多样性  功能区  无量山国家级自然保护区

Abstract:We investigated the medicinal vascular plant resources of Wuliangshan National Nature Reserve via field investigations, previous literature, and the collection and identification of plant specimens. Results showed there were 218 species of medicinal vascular plants belonging to 168 genera and 80 families, which accounted for 57.37% of total plant species. For growth forms, there were more species of herbs than of shrubs and trees. For medicinal vascular plant utilization, roots and whole herbs were the most commonly used part of the whole plant, accounting for 22.31% and 21.03% of the total, respectively. Analysis of medicinal vascular plant efficacy showed they were mostly used as antipyretics and antirheumatics and activating blood to resolve stasis. Assessment of the threatened status of the medicinal vascular plants showed that those of least concern accounted for 82.11% of the medicinal plants, which was much higher than that of other regions nation-wide and indicated that species in this region were well-preserved. Vascular plant species richness in the different functional zones of the reserve was:core zone > buffer zone > experimental zone, though the proportion of medicinal vascular plants was:core zone < buffer zone < experimental zone. Jaccard similarity analysis of medicinal vascular plants in different functional areas showed that the species in the core and experimental areas were extremely dissimilar, whereas the species in the core area and buffer area were slightly similar. This study shows that the establishment of protected areas plays an important role in the protection of the diversity of medicinal plants in Wuliangshan National Nature Reserve. Furthermore, we clarified, to a certain extent, the species composition and distribution of medicinal vascular plants, thus providing a reference for further development of protection and ethnobotany.
Keywords:Medicinal vascular plant resource  Species diversity  Functional zone  Wuliang-shan National Nature Reserve
