摘要: 根据对8个龄级杉木林下植被变化情况的调查结果,研究了杉木人工林群落学演替过程中物种多样性的变化趋势,探讨杉木林群落物种多样性与稳定性的关系。各龄级杉木林群落的物种多样性指数为2.2—3.5,均匀度为O.64—O.85,生态优势度值为O.04—0.18。该项研究,为开展生物多样性保护和持续利用提供科学依据。

Abstract: Based on the investigation in 8 age-class stands (from age 0.3 to 37 years old)in Huitong,Hunan,the changing process of species diversity of the Chinese fir plantation community was studied,the relationship between species diversity and community stabil-ity was also discussed.The results showed that the species diversity index of each age-class stand is 2.2—3.5 and the evenness is 0.64—O.85,the ecological dominant values is 0.04—O.18.The study would provide scientific basis for biodiversity conservation and sustainable utilization of the artificial forest.
