River floodplains are hotspots of productivity and biodiversity and recognized to fulfil vital ecosystem functions and services. Restoration measures of the decoupled Danube floodplains east of Vienna aim to re‐establish multi‐functionality, that is, ensure navigation, preserve and restore unique fluvial and riparian habitats and re‐establish natural processes and service provisioning. Side‐channels are proposed for reconnection combined with the removal of embankments and groins. We evaluated how a programme of measures influences the diversity and quantity of specific ecosystem services (ES) and therefore, the overall multi‐functionality of the floodplain compared to the current situation. Therefore, regulating ecosystem services (RES), such as nutrient retention and habitat provisioning, were modelled and predicted using multivariate regression models. Also, the potential of cultural ecosystem services (CES) was assessed based on mapping of recreational activities. The impact of proposed measures on ES quantity, that is, quantitative spatial representation, and quality, that is, biodiversity and nature experience, as well as potential synergies and trade‐offs were analysed. Our results show clear synergies especially for RES (habitat for the rheotopic community and nutrient retention) and the CES of nature experience. Those services have a weak and local trade‐off with the quantitative availability of opportunities for recreation. This pattern could only be detected by considering both, quantitative as well as qualitative aspects of ES. Overall, our results show that the restoration measures have a high potential to increase the multi‐functionality of the floodplain system by supporting the provisioning of RES including habitat for endangered species and selected CES.

通过考虑生态系统服务质量,数量和权衡取舍,分析恢复洪泛区系统多功能性的潜力

洪泛区是生产力和生物多样性的热点地区,被认为可以履行重要的生态系统功能和服务。维也纳以东分离的多瑙河洪泛区的恢复措施旨在重新建立多功能性,即确保航行,保存和恢复独特的河流和河岸生境,并重新建立自然过程和服务提供。建议使用旁通道进行重新连接,并去除路堤和腹股沟。我们评估了一项措施计划如何影响特定生态系统服务(ES)的多样性和数量,因此评估了与当前情况相比,洪泛区的整体多功能性。因此,调节生态系统服务(RES),例如养分保留和栖息地供应,使用多元回归模型进行建模和预测。此外,根据娱乐活动的绘图评估了文化生态系统服务(CES)的潜力。分析了拟议措施对ES数量(即空间定量表示和质量,即生物多样性和自然经验)的影响,以及潜在的协同作用和权衡。我们的结果显示出明显的协同作用,特别是对于RES(流变群落和营养物保留的栖息地)和自然体验的CES。这些服务在地方上难以取舍,并且在娱乐机会上的数量可得。仅通过考虑ES的定量和定性方面,才能检测到这种模式。总体,
