湘西南龙底保护区药用种子植物功效组成特征及资源评价

Effect Composition Characteristics and Resource Assessment of Medicinal Seed Plants in Longdi Nature Reserve in Southwestern Hunan

分析了龙底自然保护区药用种子植物种类、药用功效与采摘部位组成特征,并进行了资源评价。结果表明,龙底自然保护区有药用种子植物174科579属879种,分别占该区植物区系的92.55%、66.63%和40.43%,占全国药用种子植物种类的16.16%。879种药用植物中,木本占47.90%。药用功效覆盖了21大类疾病的防治领域;平均每种植物具有5.31类药用功效;药用植物既具专用性,也具广谱性。植物的枝、叶等10种植物器官都可以作为药用材料,以根及根皮和全株的植物种类所占比例最大。药用植物资源具有丰富的基因多样性、物种多样性、药用功效多样性和植物器官利用的多样性,有很高的药用价值。它既是中药材泡制的重要原料,又是医学工业生产的重要原料。同时,提出了药用植物可持续利用的建议。

The medicinal plants of the Longdi Nature Reserve from the seeds of medicinal plant species ,medicinal function and picking parts of the plants, and the medicinal plant resources in Longdi Nature Reserve were analyzed and evaluated. The result showed ： In the area, there are medicinal plant seeds in 879 species 579 genus 174 families, covering 92.55%, 66.63% and 40.43% of the area flora respectively, eoveringl6.16% of medicinal plant seeds of whole country. In the 879 species of medicinal plants ,woody covers 47.90%. The medicinal effect covers 21 categories of medicinal prevention and treatment of disease and average for each type of plant has 5.31 medicinal functions. Therefore ,medicinal plants have both specificity, but also a broad spectrum. 10 species of plant organs, such as branches,leaves, roots, root skin and the whole plant, can be used as medicinal materials, which take the largest proportion in the whole plant. The resources of medicinal plants is rich in genetic diversity, species diversity, medicinal use of diversity and the diversity of plant organs have a high medicinal value. It is an important raw material of Chinese herbal medicines brewed, but also an important industrial raw material medicine. Meanwhile, in this paper, the sustainable use of medicinal plants were also recommended.
