Health and sustainability can be measured and defined in terms of: (1...
متن کاملModelling forest ecosystems: the Edinburgh Forest Model
Reasons for building an ecosystem model are discussed, stressing the importance of objectives. A model is required for any research programme aiming to take a firm grasp of forest responses. The Edinburgh Forest Model (EFM) is outlined. This is a standard model of the genre, taking account of pools and fluxes of carbon (C), nitrogen (N) and water. It comprises tree, soil and water submodels. Th...
