Though the Ecosystem Service (ESS) approach is considered promising for integrated ecosystem management, its operationalisation is hampered by the lack of agreed evaluation instruments. To demonstrate the suitability of a structured ESS evaluation, we conducted a case study estimating the impact of the restoration of the Emscher River and its tributaries on the provision, use and benefit of ESS. The Emscher restoration is a large-scale project with immense temporal and financial efforts. To assess the values generated by this restoration, we applied an ESS evaluation framework and quantified the regulation and maintenance ESS ‘self-purification capacity’, ‘maintaining nursery populations and habitats’ and ‘flood protection’ as well as cultural ESS such as aesthetic, recreational, educational and existence values. Final ESS were monetized using economic methods, e.g. ‘damage costs avoided’, ‘contingent valuation’ and ‘benefit transfer’. We estimated a market value/direct economic impact of 21,441,572 € per year as a result of the restoration. Furthermore, a non-market value for people who care about the local environment of 109,121,217 € per year was determined, representing the benefit with ‘non-use value’ from the Emscher restoration. Our case study demonstrated the successful application of the structured evaluation framework in practice. Its implications and limitations are discussed.

尽管生态系统服务（ESS）方法被认为对综合生态系统管理很有前途，但由于缺乏商定的评估工具，其运行受到了阻碍。为了证明结构化ESS评估的适用性，我们进行了一个案例研究，估算了Emscher河及其支流的恢复对ESS的提供，使用和收益的影响。Emscher修复工程是一项大规模的项目，需要大量的时间和财力。为了评估此修复所产生的价值，我们应用了ESS评价框架，并对ESS的“自我净化能力”，“维持苗圃人口和栖息地的维护”，“防洪”以及文化ESS（例如美学，娱乐，教育和生存价值观。最终的ESS通过经济方法获利，例如“避免的损失成本”，“或有评估”和“收益转移”。我们估计修复后，每年的市场价值/直接经济影响为21,441,572欧元。此外，对于关心当地环境的人们，每年确定的非市场价值为109,121,217欧元，这代表了Emscher修复带来的“非使用价值”带来的收益。我们的案例研究证明了结构化评估框架在实践中的成功应用。讨论了它的含义和局限性。
