Abstract:

Castanopsis hystrix is one of the important species of south subtropical evergreen broad-leaved forest in Fujian Province.With the method of spatial series substituting for time series,its population structure was analyzed in Daoshi mountain and the results showed that growing and declining type of population structure existed.The study on spatial distribution pattern by using five aggregate indices indicated that the type of distribution pattern was random,and further analysis with Iwao's M^*-X regression suggested that the basic component of distribution was individual.Population dynamics analysis showed the spatial distribution pattern changed from aggregate type to random type during the course of population growth.

Key words: Castanopsis hystrix, Population structure, Spatial distribution pattern
