我们评估了哥斯达黎加的环境服务付费计划（PSA），这是在20世纪90年代末成立的意图，实施和影响。向拥有林区土地的私人土地所有者支付款项，以表彰其土地提供的生态系统服务。为了描述哥斯达黎加PSA的分布特征，我们将遥感与地理信息系统数据库相结合，然后使用计量经济学来探讨支付对森林砍伐的影响。付款广泛分布在生态和社会经济梯度上，但1997-2000年，在收到付款的地区，森林砍伐率并没有明显降低。哥斯达黎加其他成功的保护政策，包括PSA计划之前的政策，可以解释目前森林砍伐率的下降。PSA计划是全球生态系统投资制度化的一个重大进步，因为很少有其他国家有这样的保护历史，因为可以从哥斯达黎加的经验中学到很多东西。
We evaluated the intention, implementation, and impact of Costa Rica's program of payments for environmental services (PSA), which was established in the late 1990s. Payments are given to private landowners who own land in forest areas in recognition of the ecosystem services their land provides. To characterize the distribution of PSA in Costa Rica, we combined remote sensing with geographic information system databases and then used econometrics to explore the impacts of payments on deforestation. Payments were distributed broadly across ecological and socioeconomic gradients, but the 1997-2000 deforestation rate was not significantly lower in areas that received payments. Other successful Costa Rican conservation policies, including those prior to the PSA program, may explain the current reduction in deforestation rates. The PSA program is a major advance in the global institutionalization of ecosystem investments because few, if any, other countries have such a conservation history and because much can be learned from Costa Rica's experiences.
