Determining the Potential Distribution of Vegetation, Crops and Agricultural Productivity

摘要: The terrestrial biosphere component of the Integrated Model to Assess Greenhouse Effect (IMAGE 2.0) uses changes in land cover compute dynamically greenhouse gas fluxes between and atmosphere. Potential for both natural ecosystems agrosystems, are determined with Terrestrial Vegetation (TVM). TVM consists separate submodels water-balance, global vegetation patterns, crop distribution potential rain fed yield. All these based on local climatic, hydrological soil characteristics appropriate data bases those parameters collected or compiled. structure all models, linkages them other modules IMAGE 2.0 described. Although computationally demanding, models give an adequate description agricultural patterns. only discrepancy occurs regions where depends causes than such as additional water storage supply, anthropogenic influence disturbance. Despite this discrepancy, we conclude that simulates satisfactory it can be adequately integrated 2.0.
