目的研究陕西省旬阳县药用孢子植物资源分布及特点,为该地域植物的资源保护提出对策。方法通过实地调查和结合有关文献研究,对旬阳县的药用孢子植物的资源状况进行归纳总结。结果确定陕西省旬阳县药用孢子植物分为大型真菌、蕨类、藻类、地衣、苔藓5类,64科,92属,154种。蕨类和真菌的种数占总数的75%,海拔在1000米~2000米的种类占65%,生境在林地、树干和树皮的占66%,伞菌科、多孔菌科、铁线蕨科等10科的种数只占总数的16%,大部分为单一科属。结论该地区药用孢子植物资源丰富,自然林是其主要资源库,保护天然林是保护药用孢子植物资源的主要途径。
Objective To study the distribution and characteristics of medicinal spore plant resources in Xunyang County, Shaanxi Province, and to put forward countermeasures for resource conservation of the plant in this area. Methods Based on the field investigation and the related literatures, the resource status of medicinal spore plants in Xunyang County was summarized. The results showed that the medicinal spore plants in Xunyang County of Shaanxi Province were divided into 5 categories, 64 families, 92 genera and 154 species, including macrofungi, ferns, algae, lichens and moss. Ferns and fungi accounted for 75% of the total number of species, an elevation of 1000 meters to 2000 meters accounted for 65% of species, habitat in woodland, tree trunks and bark accounted for 66%, toadstool Division, Polyporus Branch, Branch families such as 10 species accounted for only 16% of the total, mostly single genus. Conclusion The medicinal spore plants in this area are rich in resources. Natural forests are the main resource of them. Protecting natural forests is the main way to protect medicinal spore plants.
