摘要

<正>应用频次分析方法研究了松材线虫萎蔫病病死木和林分中原有松树的空间分布型。松材线虫萎蔫病病死木在马尾松林内的分布为聚集分布 ,主要为波松 -二项分布。林分内原有松树的分布为随机分布 ,说明松材线虫萎蔫病病死木的聚集分布不是由林分内原有松树的分布所引起

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.
