大明山退化生态系统的垂直结构及动态研究

Study on the Vertical Structure and Dynamics of Degraded Ecosystem in Daming Mountain

对退化生态系统的层次结构、层片结构、高度级结构及其动态等进行了研究。结果表明 :群落的退化程度越严重 ,群落的层次、层片和高度级结构越简单 ;随着群落的恢复 ,群落的层次、层片和高度级结构也得到逐渐恢复 ,但各自的恢复速率是不同的 ;人为干扰和立地条件对退化生态系统的垂直结构和动态具有深刻的影响。

Layer structure,synusia structure and height- classes structure and dynamics of degraded ecosystem were studied.The results showed that the more serious the community degraded,the simpler the layers,the synusia and the height- classes structures in community were.L ayer,synusia and high- classes structures were recovering gradually with the community recovering,but their restorative rate were different.Human disturbance and site condition had deeply effect on the vertical structure and its dynamics in degraded ecosystem.
