摘要:

青藏高原拥有丰富的药用植物资源, 但目前人们缺乏对其多样性分布格局的清晰认识以及人类活动对药用植物资源影响的评估。本研究收集整理了青藏高原地区254种药用植物分布及人类活动的数据, 分析了当前青藏高原地区药用植物分布格局及其面临的威胁, 并划定出当前需要保护的优先区域。研究结果显示, 青藏高原药用植物的多样性和特有性主要集中在东部和东南部地区, 且较强的人类活动影响力与较高的药用植物多样性和特有性重叠, 这表明人类活动对药用植物多样性和特有性有着显著的影响。进一步结合生物和人类活动两方面因素的算法, 划定了保护优先区, 包括云南西北部、四川西南部和西部、青海东部及西藏中部, 这表明青藏高原现有的保护区存在大量保护空缺。基于此, 本研究提出了包括完善法律法规及政策监管, 增设保护区, 补充和完善保护植物名录, 加强科普宣传, 加强药用植物种质资源的收集、保存与开发的保护青藏高原药用植物资源的建议, 为今后保护政策的制定和保护区划定提供依据, 也借此宣传青藏高原生态保护问题, 唤起民众的保护关注。

Abstract

Aims: The Qinghai-Tibet Plateau (QTP) harbors abundant resources of medicinal plants, but the public still lacks the knowledge of the distribution pattern of medicinal plant diversity. The public also has poor understanding of the effects of human activities on the resources of medicinal plants.

Methods: In this study, we collected the distribution data of 254 medicinal plant species and quantified human activities in the QTP. Then we analyzed the diversity and endemism patterns and the effects of potential threats to medicinal plants. Finally we identified the conservation priority areas for medicinal plant resources.

Results: Our results showed that the diversity and endemism of medicinal plants in the QTP are primarily concentrated in the eastern and southeastern regions. We found that stronger human influence overlapped with higher diversity and endemism of medicinal plants, and that these human activities all had a significant impact on diversity and endemism. We further use an algorithm combining biological and human factors to identify conservation priority areas, including northwestern Yunnan, southwestern and western Sichuan, eastern Qinghai and central Tibet, which revealed that the current protected areas in the QTP do not effectively protect hotspots identified in this study, and there is an abundance of conservation gaps.

Conclusion: This study provides some suggestions on the protection of medicinal plant resources in the QTP, including improving laws, regulations and policy supervision, establishing more protection areas, supplementing the list of protected plants, strengthening the popularization of science, and promoting the collection, preservation and development of medicinal plant resources. These suggested measures will guide conservation policies and the delineation of protected areas in the future. We hope this study will publicize the serious threats of medicinal plants and arouse the attention of the public to conservation in the QTP.
