Inventory and Catalogue of Wetlands

Wetlands provide global services and benefits as important as the role they play in the hydrological cycle or in the global climate, although such benefits are not always obvious or easy to understand and quantify.湿地所提供的全球服务与生态效益，其重要程度可与湿地在水文循环（hydrological cycle）及全球气候中发挥的作用相提并论，尽管此类效益通常并不直观，亦难以被准确认知与量化。
