| 摘 要： | In forest growing at any one site,the growth rate of an individual tree is determined principally by its size,which reflects its metabolic capacity,and by competition from neighboring trees.Competitive effects of a tree may be proportional to its size;such competition is termed ’symmetric’ and generally involves competition below ground for nutrients and water from the soil.Competition may also be’asymmetric’,where its effects are disproportionate to the size of the tree;this generally involves ...
