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。 The hierarchical structure, stratum structure, high-level structure and its dynamics of degraded ecosystems were studied. The results showed that the more severe the community degenerated, the simpler the hierarchy, the lamella and the high-level structure of the community. With the recovery of the community, the community level, the lamella and the high-level structure also gradually recovered, but their recovery rate was Different; human disturbance and site conditions have a profound impact on the vertical structure and dynamics of degraded ecosystems.
