【摘要】：目的:调查分析西藏工布江达县珍稀药用植物种类、分布,药用部位单株平均重量、现存量、蕴藏量,药用植物功效及经济价值。方法:采用野外实地线路踏查、样点-样方套-样方调查、植物标本采集与鉴定、生物量取样及测定、市场调查及走访专家等方法。结果:工布江达县有69科234属433种植物,其中珍稀药用植物25种,适生面积共有54 933.43 hm~2。大花红景天药用部位单株平均重量最大,达25.00 g;川西小黄菊最小,仅为0.06 g。大花红景天现存量也最大,为781.25 kg/hm~2;川西小黄菊的最小,仅有0.76 kg/hm~2。25种珍稀药用植物资源蕴藏量为3 937.91 t,经济价值达10 465.91万元,单价较高的冬虫夏草和川贝母经济价值分别为844.58和221.33万元。结论:西藏工布江达县珍稀药用植物种类多、分布广、蕴藏量大、经济价值高、药理及功效独特而多样,建议加强科学研究、合理开发利用好该区珍稀药用植物资源。
[Abstract]:Objective: to investigate and analyze the species and distribution of rare medicinal plants in Gongbujiangda County, Tibet. Methods: the methods of field track survey, sampling spot, sample cut-sample investigation, plant specimen collection and identification, biomass sampling and measurement, market investigation and visiting experts were used. Results: there are 433 species of 69 families, 234 genera and 43 species of plants in Gongbujiangda County, of which 25 species are rare medicinal plants, with a suitable area of 54 933.43 hm~2.. The average weight of single plant in the medicinal part of Rhodiola davidiola was the largest, reaching 25.00 g, while that in western Sichuan was only 0.06 g. The standing stock of Rhodiola davidiola was also the largest, which was the smallest in 781.25 kg/hm~2; of small yellow chrysanthemum in western Sichuan, and only 0.76 kg/hm~2.25 species of rare medicinal plant resources were stored in 3 937.91 t, and the economic value was 104.6591 million yuan. The economic value of Cordyceps sinensis and Cordyceps spp. with higher unit price was 844.58 yuan and 2.2133 million yuan respectively. Conclusion: there are many species of rare medicinal plants in Gongbujiangda County, Tibet, with large reserves, high economic value, unique pharmacology and diverse efficacy. It is suggested that scientific research should be strengthened and the resources of rare medicinal plants in this area should be rationally exploited and utilized.
