| Summary: | The process-based biogeochemical model Biome-BGC was
enhanced to improve its ability to simulate carbon, nitrogen, and water
cycles of various terrestrial ecosystems under contrasting management
activities. Biome-BGC version 4.1.1 was used as a base model. Improvements
included addition of new modules such as the multilayer soil module,
implementation of processes related to soil moisture and nitrogen balance,
soil-moisture-related plant senescence, and phenological development.
Vegetation management modules with annually varying options were also
implemented to simulate management practices of grasslands (mowing,
grazing), croplands (ploughing, fertilizer application, planting,
harvesting), and forests (thinning). New carbon and nitrogen pools have been
defined to simulate yield and soft stem development of herbaceous
ecosystems. The model version containing all developments is referred to as
Biome-BGCMuSo (Biome-BGC with multilayer soil module; in this paper,
Biome-BGCMuSo v4.0 is documented). Case studies on a managed forest,
cropland, and grassland are presented to demonstrate the effect of model
developments on the simulation of plant growth as well as on carbon and
water balance. |
