| 摘 要： | 在闽粤栲样地调查数据的基础上，运用方差均值比（C）、丛生指数（I）、扩散指数（Ib）、Cassie指数（Ca）、平均拥挤度与平均密度的比值（M·／x）和1wao回归方程对天然闽粤栲种群的空间分布格局进行分析．结果表明：闽粤栲的空间分布格局呈聚集分布，并且随着取样面积的减少，其聚集强度逐渐增强．

| Abstract: | Based on the sample survey data of Castanopsis fissa, the spatial distribution pattern of the population of Castanopsisi fissa was analyzed by using six methods： variance to mean ratio （C）, clumping index （I）, diffusion index （18） , Cassie index （ Ca ） , average crowded degree and the ratio of average density （ M·/x） and Iwao regression equations. The results showed that the spatial pattern of Castanopsis fissa was aggregation distribution, and the aggregation intensity increased gradually with decreased sampling area. |
