| | Case | Scale | Ecosystem type | Framework and content |
| | Millennium ecosystem assessment | Global | Ecosystems were divided into 13 types: Mediterranean forests, woodlands, and scrub; temperate forest steppe and woodland; temperate broadleaf and mixed forests; tropical and subtropical dry broadleaf forests; flooded grasslands and savannas; tropical and subtropical grasslands, savannas, and shrublands; tropical and subtropical coniferous forests; deserts; montane grasslands and shrublands; tropical and subtropical moist broadleaf forests; temperate coniferous forests; boreal forests; tundra. | Assessment focused on the linkages between ecosystems and human well-being and, in particular, on ecosystem services, examined the ecosystem changes affecting human wellbeing, and discovered the critical factors causing ecosystem changes, and put forward the measures managing ecosystems sustainably. |
| | National ecosystem assessment in the US | National | Ecosystems were divided into six types: farmland, forests, grassland and shrublands, freshwater, urban, and coastal and marine. | Assessment focused on the distribution and pattern, chemical and physical characteristics, biological components, substance supply, and ecosystem service. |
| | National ecosystem assessment in the UK | National | Ecosystems were divided into eight types: forests, coastal, marine, mountain-moorland-heath, seminatural grasslands, enclosed farmland, open freshwater waters, urban, and wetlands-floodplains. | Assessment focused on the ecosystem service, material supply, driving force of ecosystem change, and human wellbeing. |
| | National ecosystem assessment in China | National | Ecosystems were divided into eight types: forests, shrublands, wetlands, grassland, farmland, urban, desert, glacier and bare land. | Assessment focused on the ecosystem distribution and pattern, service, quality, problems, driving factors. |
