对青海大通北川河源区自然保护区的资源植物进行调查,应用丰富度、均匀度、多样性指标分析了食用植物、油脂植物、饲用植物、药用植物、材用植物、鞣料植物、芳香植物、纤维植物、环保类植物、蜜源植物等10类资源植物的多样性水平。结果表明:药用植物丰富度最高,丰富度指数R值达49.850 33,环保类植物次之,蜜源植物最低;环保类植物均匀度最高,J值为0.064 914,药用植物次之,蜜源植物最低;药用植物多样性指数最高,H’值为0.362 267,环保类植物次之,蜜源植物最低。由此可见,青海大通北川河源区自然保护区药用植物多样性高于其他资源植物,开发利用前景最好。
The resource plants in Heyuan Nature Reserve of Beichuan, Datong, Qinghai, China were investigated. The edible plants, oil plants, forage plants, medicinal plants, timber plants, tanned plants and aromatic plants were analyzed with the indices of richness, evenness and diversity Plants, fiber plants, environmental plants, nectar plants and other 10 kinds of resources, plant diversity levels. The results showed that medicinal plants had the highest degree of richness, the richness index R was 49.85033, followed by the green plants and the nectar plants were the lowest. The evenness of the plants was the highest, with a J value of 0.064 914, followed by medicinal plants and nectar plants Lowest; medicinal plant diversity index highest, H ’value of 0.362 267, followed by environmental protection plants, nectar plants the lowest. Thus, the diversity of medicinal plants in Heyuan Beitaihe Nature Reserve in Datong, Qinghai Province is higher than that of other resource plants, and the prospect of development and utilization is the best.
