【摘要】 青冈种群各径级样木叶、枝、干的热值随径级不同而异 .实生与萌生样木相同径级相同器官的热值也有所不同 .实生样木各径级叶、枝、干的热值均大于萌生样木 ,且随着径级的增大而差异减小 .各层次样木的热值均表现为 :叶 >枝 >干更多还原

【Abstract】 Caloric values of leaf,branch and stem are different with various diameter classes of Cyclobanopsis glauca population. To the same trophic organ in the same diameter class, the seedling’s caloric value is greater than that of coppice, and the difference between them decreases with the increase of diameter classes. Caloric values of various layers of Cyclobanopsis glauca population trophic organs shows: leaf>branch>stem.更多还原
