Abstract

Decisions about natural resource management are frequently complex and vexed, often leading to public policy compromises. Discord between environmental and economic metrics creates problems in assessing trade-offs between different current or potential resource uses. Ecosystem accounts, which quantify ecosystems and their benefits for human well-being consistent with national economic accounts, provide exciting opportunities to contribute significantly to the policy process. We advanced the application of ecosystem accounts in a regional case study by explicitly and spatially linking impacts of human and natural activities on ecosystem assets and services to their associated industries. This demonstrated contributions of ecosystems beyond the traditional national accounts. Our results revealed that native forests would provide greater benefits from their ecosystem services of carbon sequestration, water yield, habitat provisioning and recreational amenity if harvesting for timber production ceased, thus allowing forests to continue growing to older ages.

摘要

自然资源管理决策往往复杂且棘手,常常导致公共政策妥协。环境和经济指标之间的不和谐导致在评估不同当前或潜在资源用途之间的权衡取舍时出现问题。生态系统核算方法按照国民经济核算方法对生态系统及其对人类福祉的效益进行量化,为显著推动政策进程提供了令人兴奋的机会。我们通过明确和空间链接人类和自然活动对生态系统资产和服务及其相关产业的影响,在区域案例研究中推进了生态系统核算方法的应用。这证明了生态系统除了传统国民核算之外的贡献。我们的研究结果表明,如果停止采伐木材以用于生产,那么原生林将通过其碳封存、水源涵养、生境供应和娱乐设施等生态系统服务提供更大的效益,从而使森林继续生长到更老的年龄。
