热带植物提供的生态系统服务维持着当地社会的生存，并对全球经济作出重大贡献。许多类型的生态系统服务往往来自单一的植物物种，这就有可能造成森林使用者之间的紧张关系。尽管森林使用者可能对如何使用植物有不同的方法，但在了解植物物种的可持续性如何受到关于其效用的相反观点的影响方面却做得很少。本文利用植物的固有特性，从商业伐木者和土著人民的角度提出了比较植物物种价值的概念方法。使用供应生态系统服务与样本的植物从鲁普努尼，圭亚那南部，商业伐木和生计使用指数，比较植物物种可能被认为是热带森林管理的两个对立的观点。分析表明，超过84%的植物的生存价值指数大于采伐指数。这项研究表明，通过审查对森林管理的相反做法，并采用指数来记录不同用户如何对待植物，森林管理人员可以开始回答关于在空间的什么地方以及应该为哪些物种进行养护和管理工作的问题。土著人民及其盟友可利用本文提出的方法，就其利用森林资源进行养护和支付REDD+等生态系统服务举措的费用作出空间优化决策。
The ecosystem services derived from tropical plants sustain local societies and make significant contributions to the global economy. Often many types of ecosystem services are derived from a single plant species, introducing the potential for tensions between forest users. Despite the potential for forest users having different approaches to how a plant is used, little has been done to understand how a plant species’ sustainability may be impacted by opposing views on their utility. In this paper, the inherent properties of plants were used to propose a conceptual approach for comparing the values of plant species from the perspectives of commercial loggers and indigenous peoples. Using the provisioning ecosystem services associated with a sample of plants from the Rupununi, Southern Guyana, commercial logging and subsistence use indices were developed to compare how plant species may be perceived by the two opposing views of tropical forest management. The analysis suggested that for more than 84% of plants the subsistence value indices were greater than the logging indices. This study suggested that by examining opposing approaches to forest management, and adopting indices to document how different users approach plants, forest managers can begin to answer questions on where in space, and for which species, conservation and management efforts should be pursued. The methods proposed in this paper can be used by indigenous peoples and their allies to make spatial optimization decisions on their use of forest resources for conservation and payment for ecosystem services initiatives such as REDD+.
