本文分析了印度喜马拉雅地区药用植物（MPs）的各个方面的现有信息。在已查明的知识差距中，缺乏对威胁的客观评估被认为是确定保护优先事项的主要障碍。本文在考虑到用户（工业）的需求和学者（生物学家）的保护关注的情况下解决了这个问题。因此，制定了一种优先考虑MPs保护的方法。优先排序基于三个指标：(i)使用价值指数（UVI）表明用户施加的威胁，（ii）敏感性指数（SI）反映生物学家对保护的关注，（iii）重要性值指数（IVI）是(i)和（ii）的累积值，以防止有偏见的方法。制药业对现有库存的依赖仅为10%，而且对非本地元素的依赖也表明，真正的喜马拉雅MPs的潜力尚未得到利用。然而，对专属野生品种的依赖增加（64.6%），破坏性收获趋势占主导地位（69%）以及行业使用的大多数MPs的分布范围有限，表明威胁的强度。这篇论文列出了20位对每种生命形式进行保护的顶级议员。(C) 2000 Elsevier Science Ltd.版权所有。
The paper analyses available information on various aspects of medicinal plants (MPs) of the Indian Himalaya region (IHR). Among the identified gaps in knowledge, lack of objective assessment of threats was considered a major impediment in setting conservation priorities. The paper addresses this issue keeping in view the needs of users (industry) and conservation concerns of academics (biologists). An approach for prioritisation of MPs for conservation was thus developed. Prioritisation based on three indices: (i) use value index (UVI) indicate threats imposed by users, (ii) sensitivity index (SI) reflect conservation concerns of biologists, and (iii) importance value index (IVI) is the cumulative value of (i) and (ii) to prevent biased approach. Dependence of pharmaceutical industry on only 10% of the available stock and that too on non-native elements suggest that the potential of true Himalayan MPs has not been harnessed as yet. However, increased dependence on exclusive wild forms (64.6%), dominance of destructive harvest trend (69%) and restricted distribution range of most MPs used by the industry is a pointer to the intensity of threat. The paper identifies 20 top ranking MPs for conservation in each life form. (C) 2000 Elsevier Science Ltd. All rights reserved.
