生态系统和生物多样性为社会带来好处，但其中许多好处难以量化。例如，目前尚不清楚欧洲社会是否从拥有高本土生物多样性的河流中获益。如果不了解这些情况，就很难证明对注重生态的河流管理计划进行货币投资是合理的。本研究的目的是揭示如何在四个欧洲国家的公众价值观国内河流的生态特征和假设的河流流域管理计划，旨在改善河流生态系统，特别是鱼类生物多样性的结果。我们在挪威、瑞典、德国和法国的人群中进行了选择实验。我们发现类似的偏好结构，在所有国家的高边际意愿支付改善非生物河流属性（增加可及性的河岸，改善洗澡水质，减少河流碎片）。公民还受益于某些鱼类物种发生在一条河流与本地鲑鱼物种比非本地人，特别是在挪威，并从河流的本地生物多样性的程度。为选定的河流流域管理计划（政策情景）计算的福利措施显示，主要来自生态河流管理的社会效益，而一个方案，重点是水力发电产生的效用最低。我们的结论是，生态河流管理可能会产生很高的非市场经济效益，在所有的研究国家，特别是通过非生物河流属性的管理和恢复下降或灭绝的鱼类物种。我们的研究结果有助于通过展示这些措施对公众的好处，为恢复工作的决策提供信息。
Ecosystems and biodiversity produce benefits to society, but many of them are hard to quantify. For example, it is unclear whether European societies gain benefits from experiencing rivers that host high native biodiversity. Without such knowledge, monetary investments into ecologically oriented river management plans are difficult to justify. The objective of this study was to reveal how the public in four European countries values ecological characteristics of domestic rivers and the outcomes of hypothetical river basin management plans designed to improve river ecosystems, particularly fish biodiversity. We conducted a choice experiment among the populations in Norway, Sweden, Germany, and France. We found similar preference structures in all countries with high marginal willingness-to-pay for improvements of abiotic river attributes (increased accessiblity of the river banks, improved bathing water quality, decreased river fragmentation). Citizens also benefited from certain fish species occurring in a river with native salmonid species being more valued than nonnatives, particularly in Norway, and from the degree of a river’s native biodiversity. Welfare measures calculated for selected river basin management plans (policy scenarios) revealed societal benefits that were primarily derived from ecological river management whereas a scenario focusing on hydroelectricity production generated the lowest utility. We conclude that ecological river management may produce high nonmarket economic benefits in all study countries, particularly through the management of abiotic river attributes and the restoration of declining or extinct fish species. Our results help to inform decisions on restoration efforts by showcasing the benefits that these measures have for the public.
