Abstract:
This paper deals with the spatial distribution patterns of the dead pine trees of pine wilt nematode disease and that of original pine trees (living pine trees plus dead pine trees) with the method of frequency distribution analysis.The results indicate that the spatial distribution pattern of the dead pine trees in masson pine woods is the aggregation distribution pattern,mainly Poisson Binomical distribution.The spatial distribution pattern of the original pine trees is Poisson distribution.This suggest that the aggregation distribution pattern of the dead pine trees is not caused by the spatial distribution pattern of the original pine trees.
