Wetlands play an important role in the provision of important ecosystem services like the provision of clean water to the world, adaptation to climate change, and support for biodiversity; although they are sometimes also associated with adverse climate effects. Wetlands are, however, currently grossly underrepresented in global environmental models. In this paper, we explore the required functionality of a generic model of the effects of climate and land-use changes on wetlands ecosystem services worldwide. We briefly review existing models to identify elements which can be combined to compile a generic wetland model.

The proposed global wetland model should be integrated into and receive data from existing hydrology and climate models. Wetland delineation can be based on local hydrological and topographical conditions and verified with global wetland databases. We conclude that an integrated approach combining hydrology, biogeochemistry and vegetation for wetlands is not available yet, however, useful building blocks exist that can be combined.

湿地在提供重要的生态系统服务中发挥重要作用，例如向世界提供清洁水，适应气候变化以及对生物多样性的支持；尽管它们有时还与不利的气候影响有关。但是，目前湿地在全球环境模型中的代表性严重不足。在本文中，我们探索了气候和土地利用变化对全球湿地生态系统服务影响的通用模型的必需功能。我们简要回顾一下现有模型，以识别可以组合起来的通用湿地模型。

拟议的全球湿地模型应整合到现有水文和气候模型中并从中获取数据。湿地划定可以基于当地的水文和地形条件，并通过全球湿地数据库进行验证。我们得出的结论是，尚无将湿地的水文，生物地球化学和植被相结合的综合方法，但是，存在可以组合的有用构件。
