茫荡山自然保护区甜槠群落物种多样性研究

采用物种丰富度Margalef指数R、优势度Simpson指数D、Shannon-Wiener多样性指数H、Pielou均匀度指数J与群落优势度指数C对茫荡山国家级自然保护区甜槠群落物种多样性指数进行计算。结果表明,茫荡山国家级自然保护区甜槠群落乔木层物种多样性指数R、D、H、J与C分别为2.4 843、0.8 126、1.9 801、0.8 258与0.1 874;灌木层物种多样性指数R、D、H、J与C分别为4.0 944、0.8 973、2.5 377、0.9 153与0.1 027。群落物种组成以甜槠、木荷和马尾松为优势种群,研究为茫荡山自然保护区甜槠群落特征研究提供理论依据。

Study on the Species Diversity of Castanopsis eyrei Community inmangdangmountain Nature Reserve

The species diversity of Castanopsis eyrei community inmangdangmountain National Nature Reserve was studied by applying the indices ofmargalef richness index R, Simpson domination index D, Shannon-Wiener diversity index H, Pielou evenness index Js and community dominance index C. The results showed that the R,D ,H,J and C in tree layer of C. eyrei community inmangdangmountain National Nature Reserve were 2.4 843,0,8 126,1.9 801,0,8 258 and 0,1 874, respectively. The R,D,H,J and C in shrub layer of C eyrei community inmangdangmountain Nature Reserve were 4.0 944,0.8 973,2.5 377,0.9 153 and 0.1 027, respectively. The community dominated by C eyrei, Schima superba and Pinusmassoniana, which could provide a theoretic basis for the research of C. eyrei community characteristics inman~dan~mountain National Nature Reserve.
