Abstract：
Successful implementation of the Kunming-Montreal Global Biodiversity Framework requires identifying a process for measuring and valuing changes in biodiversity that build on the recognition that economics and valuation must play a key role in \"halting and reversing\" biodiversity loss. Here, we discuss considerations for a practical path to valuing changes in biodiversity. Framing changes in the value of biodiversity as a summary of changes in certain natural assets enables leveraging existing approaches and international standards associated with environmental-economic accounting. We discuss why an approach that builds from individual species, evolutionary groups, or functional groups into a practical, hierarchical statistical classification system is better than the development of any one biodiversity index. We merge techniques from ecology and other natural sciences, national and environmental-economic accounting, and economics, which are all on the cusp of making measurement of the change in the value of biodiversity possible. The focus should be on scaling and integrating these approaches. The path forward appears to begin with imperfect but useful measures, grounded in robust concepts, while establishing ambition to further scale-up measurements-just like the past evolution of many other official statistical series.
摘要：
成功实施《昆明-蒙特利尔全球生物多样性框架》需要确定一个衡量和评估生物多样性变化的过程，该过程建立在认识到经济学和评估必须在“制止和扭转”生物多样性丧失方面发挥关键作用的基础上。这里,我们讨论了评估生物多样性变化的实用路径的考虑因素。将生物多样性价值的变化作为某些自然资产变化的总结，可以利用与环境经济核算相关的现有方法和国际标准。我们讨论了为什么从单个物种构建的方法，进化群体，或功能组到一个实用的，分层统计分类体系的发展优于任何一种生物多样性指数。我们融合了生态学和其他自然科学的技术，国家和环境经济核算，和经济学,所有这些都处于使测量生物多样性价值变化成为可能的风口浪尖。重点应该是扩大和整合这些方法。前进的道路似乎始于不完善但有用的措施，植根于强大的概念，同时确立了进一步扩大测量规模的雄心-就像许多其他官方统计系列的过去演变一样。
