摘要环境服务付费（PES）是一种很有前景的环境保护机制。PES可以为保护区提供额外的资金，或者支付土地使用者保护保护区以外的生物多样性，或者两者兼而有之。PES需要安全的长期资金来源才能有效运作。然而，为生物多样性保护直接获得资金是困难的。在大多数情况下，用水者是最有可能的直接或间接来源。因此，PES帮助保护生物多样性的潜力在很大程度上取决于保护供水服务的兴趣领域与保护生物多样性的兴趣领域重叠的程度。本文考察了危地马拉高地这种重叠的程度。结果表明，这一潜力在国内差别很大，一些生物多样性保护优先地区有很好的获得支付的潜力，而其他地区则很少或没有。总的来说，大约四分之一的生物多样性保护优先地区有可能获得资助。因此，PES远不是生物多样性保护的灵丹妙药，但它们可以为这一目标作出有意义的贡献。
Abstract Payments for environmental services (PES) are a promising mechanism for conservation. PES could either provide additional funding for protected areas, pay land users to conserve biodiversity outside protected areas, or both. PES require a secure long-term source of financing to work effectively. Obtaining payments directly for biodiversity conservation is difficult, however. In most cases, water users are the most likely source, either directly or indirectly. Thus the potential for PES to help conserve biodiversity depends, in a large measure, on the degree to which areas of interest for conservation of water services overlap with areas of interest for conservation of biodiversity. This paper examines the extent of such an overlap in the case of highland Guatemala. The results show that this potential varies substantially within the country, with some biodiversity conservation priority areas having very good potential for receiving payments, and others little or none. Overall, about a quarter of all biodiversity conservation priority areas have potential for receiving payments. Thus PES are far from being a silver bullet for biodiversity conservation, but they can make a meaningful contribution to this objective.
