摘要
采用样方相邻格子法,对闽清白云山林场22年生杉木生态公益林群落结构进行调查;运用多样性指数和改进的Godron M稳定性测定方法,对该群落生物多样性和稳定性进行研究。结果表明:样地内共有维管束植物59科89属127种,其中乔木层有13科16属17种,灌木层有38科57属90种,草本层有21科28属29种;物种丰富度、多样性指数和均匀度指数的大小均表现为灌木层>草本层>乔木层,优势度指数大小则表现为乔木层>草本层>灌木层;白云山杉木生态公益林处于演替过程中,群落接近稳定状态。
The community characteristics investigation of Cunninghamia lanceolata ecological service forest of Baiyun Mountain in Minqing was taken out with contiguous grid quadrats method. The biodiversity and stability of the community were researched by diversity indices and the improved M-Godron method. The results showed that,there are 127 species of vascular plants belonging to 59 families and 89 genera in the investigated quadrats with a total area of 10000 m2,17 species in the tree layer,90 species in the shrub layer,29 species in the herbaceous layer. The order of the layers of Margalef index,Shannon-Weiner index and Pielou index were all showed that: shrub layer herbaceous layer tree layer,expect the Simpson index( tree layer herbaceous layer shrub layer). The community of Cunninghamia lanceolata ecological service forest of Baiyun Mountain is in a stage of successional change,close to stable state.
