茫荡山自然保护区甜槠群落物种多样性研究

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

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。

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.
