毛竹林扩张对土壤生物群落结构的影响

The effect of Phyllostachys edulis forest expansion on soil biological community structure

毛竹作为大型克隆性植物,具有生理整合、形态可塑等克隆特性,有着很强的扩张性,可侵入邻域生态群落,并使被入侵生态系统内其他植物逐渐退出群落,威胁生态系统的稳定性。本文总结了毛竹在扩张过程中对受侵生态系统内土壤生物(土壤微生物、土壤动物等)群落结构与多样性产生的影响,以及毛竹扩张后的植被演替、地表凋落物状况、土壤环境特征与土壤生物群落结构多样性之间的关系,为毛竹林扩张的生态化控制与生态风险评估等研究提供参考,维护生态系统内生物多样性等生态服务功能的稳定与平衡。

Through clonal characteristics including physiological integration and morphological plasticity,Phyllostachys edulis as a large clonal plant can invade the neighborhood ecological community,make other plants disappear from the community gradually in the invaded ecosystem,and threat the stability of the ecosystem.The aim of this review is to summarize the effect of Phyllostachys edulis expansion on soil biological community structure,and the relationship between vegetation succession,floor litter,soil environmental characteristics and soil biological community structure diversity after expansion of Phyllostachys edulis,which can be a reference to the research of ecological control and ecological risk assessment of Phyllostachys edulis expansion,and maintain the stability and balance of ecological Service functions in the ecosystem.
