摘  要:
本研究把中心点——四分面和我们提出的“树冠权重更新面积”(TCWRA)结合起来,运用于野外植被资料的取样。在此基础上,用Markov过程描述了琅琊山森林群落线性和非线性演替,预测了平衡时群落空间各层次林木的组成状态。研究结果表明,琅琊山森林群落在没有外界大的干扰下,麻栎、化香种群将从该群落中消退,发展成以青檀、五角枫、榉树为优势种群的顶极群落。

摘  要:
In this study the tree canopy-weighted regeneration area (TCWRA) method was developed and used together with the point-centered quarter method (PCOM) in the field investigation. Mnrkov process was also used to describe linear and non-linear succession of the forest community in Langya Mountain, Anhui. The structure and dynamics of each vertical layer of the com munity in a stable state was also forecasted. The results obtainted indicate that Quercus accutissima and Platycarya strobilacea are gradually degenerated without any external disturbances. The community will develop to appraoch to " climax" with domination of Pteroceltis iatarinowii, Acer mono and Zellorov schneideriana.
