The rich diversity in medicinal plants provides an important material basic for the development of Traditional Chinese medicine in China. It is important to explore the present situation of medicinal plants within special regions in order to provide scientific instructions for their sustainable protection and exploitation and utilization. In this study, we carried out the field survey according to the guideline of national survey of Chinese material medica resources and the guideline of plant species diversity survey and estimation at county level with the line transect method. With the field surveyed data, we explored the diversity and distribution of the threatened medicinal vascular plants in Lancang. We found that there were 33 species of the threatened medicinal vascular plants in this county. These species were from 23 genera and 17 families, and were composed of one critical endangered, 10 endangered and 22 vulnerable species. They were widely distributed across the whole county and were most concentrated in the town of Nuozhadu, Fazhanhe, Nuofu and Zhutang, which were located in the southeastern, southwestern and western of Lancang, respectively. We also found that the plant species richness followed a unimodal pattern along elevation. In addition, we found that the areas of Nuozhadu Nature Reserve in Lancang only covered six threatened medicinal vascular plants, while most of the regions with high species richness were not well protected. Therefore, we proposed to make more efforts to improve the protection measurements in order to better protect and utilize the medicinal plants in Lancang.
药用植物的丰富多样性为中国中医药的发展提供了重要的物质基础。探索特殊区域内药用植物的现状，对于为其可持续保护、开发和利用提供科学指导具有重要意义。在本研究中，我们按照全国中药资源普查技术规程和县级植物物种多样性调查与评估技术规程，采用样线法进行了实地调查。利用实地调查数据，我们探究了澜沧县受威胁药用维管植物的多样性和分布情况。我们发现该县有33种受威胁药用维管植物。这些物种来自17科23属，包括1种极危、10种濒危和22种易危物种。它们广泛分布于全县，最集中在诺扎渡镇、发章河、诺富和朱堂，分别位于澜沧县的东南部、西南部和西部。我们还发现，植物物种丰富度沿海拔呈单峰模式。此外，我们发现澜沧县诺扎渡自然保护区仅涵盖6种受威胁药用维管植物，而大多数物种丰富度高的区域保护不力。因此，我们建议加大力度改进保护措施，以便更好地保护和利用澜沧县的药用植物。
