本文概述了以货币单位表示的 10 个主要生物群落的生态系统服务价值。总共筛选了 320 多份出版物，涵盖 300 多个案例研究地点。大约 1350 个价值估计被编码并存储在可搜索的生态系统服务价值数据库 (ESVD) 中。分析中使用了 665 个价值估计值。考虑到任何估值的不确定性和背景性质，分析表明，生态系统服务的总价值相当可观，范围从“平均”公顷公海可能提供的生态系统服务总价值每年 490 美元到“平均”公顷珊瑚潜在服务的近 350,000 美元/年之间 更重要的是，我们的结果表明，大部分价值都在市场之外，最好将其视为不可交易的公共利益。因此，对生态系统的持续过度开发是以牺牲穷人和子孙后代的生计为代价的。鉴于生态系统的许多积极外部性在土地用途转换后消失或大幅减少，更好地核算生态系统提供的公共产品和服务对于改善生物多样性保护和可持续生态系统管理的决策和机构至关重要。 (C) 2012 Elsevier B.V.
This paper gives an overview of the value of ecosystem services of 10 main biomes expressed in monetary units. In total, over 320 publications were screened covering over 300 case study locations. Approximately 1350 value estimates were coded and stored in a searchable Ecosystem Service Value Database (ESVD). A selection of 665 value estimates was used for the analysis.Acknowledging the uncertainties and contextual nature of any valuation, the analysis shows that the total value of ecosystem services is considerable and ranges between 490 int$/year for the total bundle of ecosystem services that can potentially be provided by an 'average' hectare of open oceans to almost 350,000 int$/year for the potential services of an 'average' hectare of coral reefs.More importantly, our results show that most of this value is outside the market and best considered as non-tradable public benefits. The continued over-exploitation of ecosystems thus comes at the expense of the livelihood of the poor and future generations. Given that many of the positive externalities of ecosystems are lost or strongly reduced after land use conversion better accounting for the public goods and services provided by ecosystems is crucial to improve decision making and institutions for biodiversity conservation and sustainable ecosystem management.
