Báo cáo toán học: "omponents of functional-structural tree models" ppt

... aspects of tree development can be modeled in terms of an elementary unit. The functional aspects of tree development are the capture of resources and the dis- tribution of growth (in terms of mass). ... development of trees; – Competition with surrounding vegetation; – Growth of trees in a mixed species stand and understo- ry seedling growth; – Tree- herbivory interactio...
