     [摘要]丰富的药用植物多样性是我国中医药事业发展的重要物质基础,摸清地区资源现状,可以为其药用资源的可持续保护和开发利用提供科学指导。该文依据《全国中药资源普查技术规范》和《县域植物物种多样性调查与评估技术指导手册》对云南省澜沧拉祜族自治县(简称“澜沧县”)开展了全县范围的中药资源普查及野生植物多样性调查与评估工作,分析了其中受威胁药用植物维管束植物的多样性及其分布特征,结果发现:全县境内共有受威胁药用维管束植物33种,隶属于17科23属,分别包括极危、濒危、易危等级的物种1种、10种、22种。这些受威胁药用维管束植物分布在澜沧县境内的不同区域,以县东南部的糯扎渡镇和发展河乡、西南部的糯福乡以及西部的竹塘乡包含的受威胁物种多样性最为丰富,且其物种丰富度随海拔的变化呈单峰格局。研究仅发现6种受威胁药用维管束植物在糯扎渡自然保护区澜沧片区内受到保护,而多数该类群物种丰富的区域尚未得到有效保护。因此,该文建议进一步完善现有保护体系,以更好地保护和利用澜沧县地区的药用植物多样性。

    [Abstract]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

    中國是生物多样性最为丰富的国家之一,境内分布有3万多种高等植物[1],其中1万多种为药用植物[23]。丰富的药用植物资源是我国中药产业及中医药事业发展的重要物质基础,是国家的战略性资源。摸清区域药用植物资源家底,有助于促进药用植物多样性的合理保护和可持续利用,促进中药产业健康发展[4]。环保、农业、林业、中医药等系统都在尽各自能力开展领域相关的生物多样性调查与评估工作。比如中医药系统先后组织开展过3次全国性的中药资源普查工作,第四次全国性的中药资源普查试点工作也于2011年开始在陆续开展[5];环保系统则更注重生物多样性的全面调查,设立生物多样性保护专项,于2016年开始陆续开展了全国范围生物多样性保护优先区内的生物多样性调查与评估工作。, 百拇医药(池秀莲 袁以凯 方波 张小波 杨涵雨 赵志平 李果 付开聪 郭兰萍 黄璐琦)
