难以确定适当的生物多样性影响衡量标准仍然是将生物多样性考虑纳入对环境负责的投资的主要障碍。我们提出并分析了一个简单的以科学为基础的本地度量：所有本地种群对全球物种丰度的贡献比例之和，并对接近灭绝的物种进行了校正。它在数学上与一个广泛使用的全球生物多样性指标--地球生命力指数相联系，我们提出了一个改进的公式，直接解决了已知的由反射引起的奇异性问题。我们表明，在一个理想的市场中，贸易在我们的度量将导致接近最优的保护资源分配，强调保护濒危物种的支持。采用的障碍很低，因为使用该指标不需要机构认证系统。与其他指标结合使用，潜在的应用领域包括生物多样性相关的财务披露和自愿或法定的生物多样性无净损失政策。
Difficulties identifying appropriate biodiversity impact metrics remain a major barrier to inclusion of biodiversity considerations in environmentally responsible investment. We propose and analyse a simple science-based local metric: the sum of the proportions that all local populations contribute to their global species abundances, with a correction for species close to extinction. It links mathematically to a widely used global biodiversity indicator, the Living Planet Index, for which we propose an improved formula that directly addresses the known problem of singularities caused by extinctions. We show that, in an ideal market, trade in our metric would lead to near-optimal conservation resource allocation, emphasising support of extinction-threatened species. Barriers to adoption are low, as use of the metric does not require an institutional certification system. Used in conjunction with other metrics, potential areas of application include biodiversity related financial disclosures and voluntary or legislated no net biodiversity loss policies.
