本文提出了一种将生态系统服务纳入财富核算框架的方法。对生态系统及其服务的核算导致对净国内生产总值(NDP)进行调整，以反映当前生态系统种群提供的直接效益，而不是它们在保护或支持经济活动、财产和人的生命方面的间接贡献。当生态系统不可逆转地转换为经济发展时，必须进一步修改NDP，以反映当前将生态资本转换为其他土地用途时发生的任何资本重估。崩溃的风险还需要对净生产总值进行调整，因为与生态系统转换相关的任何资本重估都必须根据这一风险进行调整，而且必须从净生产总值中减去与崩溃相关的生态系统贴现最低价值。以1970-2009年期间泰国红树林为例，说明了生态资本对财富账户的各种贡献。
This paper develops a methodology for including ecosystem services in a wealth accounting framework. Accounting for ecosystems and their services leads to adjusting net domestic product (NDP) for the direct benefits provided by the current stock of ecosystems but not for their indirect contributions in terms of protecting or supporting economic activity, property and human lives. When ecosystems are irreversibly converted for economic development, NDP must be further modified to reflect any capital revaluation that occurs with the current conversion of ecological capital to other land uses. The risk of collapse also requires adjustments to NDP, as any capital revaluation associated with ecosystem conversion must be adjusted for this risk, and the discounted minimum value of ecosystems associated with collapse must be subtracted from NDP. These various contributions of ecological capital to wealth accounts are illustrated with the example of mangroves in Thailand over the period 1970-2009.
