| Abstract: | 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. |
