| 摘 要： | 应用扩散型指数和回归分析方法对微红梢斑螟幼虫在湿地松和马尾松林中的空间分布进行了研究．聚集度指标说明微红梢空间分布型均属于聚集分布；回归分析说明其分布是负二项分布．个体间相互吸引，分布的基本成份为个体群，群体内分布是随机的．

| Abstract: | This paper deals with the spatial distribtion of the larvae of Dioryctria rubella in masson pine and slash pine with diffusion index and regression analysis.Aggregation indices indicate the larva distribution is aggregation distribution pattern,and regression analysis indicates its distribution is negative binomial.The larvae attract each other.The main composition of distribution is individual community.In the community,the distribution of the larvae is random. |
