摘要
应用聚集度指标、Ｉｗａｏ 方程和Ｔａｙｌｏｒ 幂法则模型等测定方法，研究了闽北次生常绿阔叶林９ 个主要树种的空间分布格局．研究结果表明，闽北次生常绿阔叶林９ 个主要树种的空间分布呈聚集分布，分布的基本成份为个体群，个体群分布聚集．根据Ｉｗａｏ 的Ｍ＊ 与ｘ 的回归方程，计算了９ 个树种在不同密度和允许误差下的理论抽样数．
The spatial distribution pattern of nine dominant trees in a secondary evergreen broad leaved forest in northern Fujian was studied using aggregate indices, Iwao's equation and Taylor's model. The results showed that the spatial distribution pattern of the nine dominant trees in the forest was aggregated pattern in population and the basic component of distribution was proved to be individual group, which approached to be aggregated pattern. According to Iwao's equation, the theoretical sampling numbers of forest survey were analyzed and calculated under different population densities and allowing errors.
