Riverine floods cause increasingly severe damages to human settlements and infrastructure. Ecosystems have a natural capacity to decrease both severity and frequency of floods. Natural flood regulation processes along freshwaters can be attributed to two different mechanisms: flood prevention that takes place in the whole catchment and flood mitigation once the water has accumulated in the stream. These flood regulating mechanisms are not consistently recognized in major ecosystem service (ES) classifications. For a balanced landscape management, it is important to assess the ES flood regulation so that it can account for the different processes at the relevant sites. We reviewed literature, classified them according to these mechanisms, and analysed the influencing ecosystem characteristics. For prevention, vegetation biomass and forest extent were predominant, while for mitigation, the available space for water was decisive. We add some aspects on assessing flood regulation as ES, and suggest also to include flood hazard into calculations.

解开生态系统服务“洪水调节”:机制和相关生态系统条件特征

河流洪水对人类住区和基础设施造成越来越严重的破坏。生态系统具有降低洪水严重程度和频率的天然能力。淡水沿线的自然洪水调节过程可归因于两种不同的机制:在整个集水区进行防洪,以及在河流中积水后缓解洪水。这些洪水调节机制在主要生态系统服务 (ES) 分类中并未得到一致认可。对于平衡的景观管理,重要的是评估 ES 洪水调节,以便它可以解释相关地点的不同过程。我们回顾了文献,根据这些机制对它们进行了分类,并分析了影响生态系统的特征。为了预防,植被生物量和森林范围占主导地位,而对于减缓,可用的水空间是决定性的。我们在评估洪水调节作为 ES 方面增加了一些方面,并建议将洪水危害纳入计算。
