River landscapes offer diverse cultural ecosystem services. Providing more information on the quantity that river landscapes provide in terms of offered cultural ecosystem services could contribute to river landscape planning. Offered cultural ecosystem services are ecosystem contribution that may provide benefits to humans. The aim of this study is to apply an indicator framework for spatially assessing offered cultural ecosystem services in German river landscapes. Our indicator framework ‘CulturAl Ecosystem Services of River landscapes’ (CAESaR) quantifies offered cultural ecosystem services at national and local scale, with adapted sets of sub-indicators with regard to the required level of detail and available spatial data. The indicator framework considers opportunities for water-related and non water-related activities, landscape aesthetic quality, and heritage. Our results show that the highly rated river landscape areas have an above-average proportion of river courses and active floodplains. Historical floodplains provide lower offered cultural ecosystem services scores overall. The land cover classes pasture, broad-leaved forest and water courses receive high offered cultural ecosystem services scores, whereas non-irrigated arable land characterizes river landscapes with low indicator scores. We conclude that the proposed indicator framework proved applicable at various scales and can be transferred to cases with a similar context.

河流景观提供多样化的文化生态系统服务。就所提供的文化生态系统服务而言，提供有关河流景观提供的数量的更多信息可能有助于河流景观规划。提供的文化生态系统服务是可能为人类带来利益的生态系统贡献。这项研究的目的是为在德国河流景观中空间评估提供的文化生态系统服务应用指标框架。我们的指标框架“河流景观的文化生态系统服务”（CAESaR）在国家和地方范围内量化了提供的文化生态系统服务，并根据所需的详细程度和可用的空间数据对子指标进行了调整。指标框架考虑了与水有关和与水无关的活动的机会，景观美学品质和传承。我们的结果表明，高评价的河流景观区的河道和活跃的洪泛区所占比例高于平均水平。历史上的洪泛区总体上提供的文化生态系统服务得分较低。土地覆盖类的牧场，阔叶林和水道获得的文化生态系统服务得分较高，而非灌溉耕地的河流景观指标得分较低。我们得出的结论是，事实证明，拟议的指标框架适用于各种规模，可以转移到具有类似背景的案例中。历史上的洪泛区总体上提供的文化生态系统服务得分较低。土地覆盖类的牧场，阔叶林和水道获得的文化生态系统服务得分较高，而非灌溉耕地的河流景观指标得分较低。我们得出的结论是，事实证明，拟议的指标框架适用于各种规模，可以转移到具有类似背景的案例中。历史上的洪泛区总体上提供的文化生态系统服务得分较低。土地覆盖类的牧场，阔叶林和水道获得的文化生态系统服务得分较高，而非灌溉耕地的河流景观指标得分较低。我们得出的结论是，事实证明，拟议的指标框架适用于各种规模，可以转移到具有类似背景的案例中。
