| 摘 要： | weibull分布的概率密度函数为f（x）=c/b（x-a）~（c-1）exp （-（x-a）~c/b）,x≥a。本文首次用于拟合马尾松毛虫种群的空间分布,9批抽样数据拟合结果表明马尾松毛虫越冬代大幼虫、越冬代蛹的空间分布符合Weibull分布,从而丰富了马尾松种群空间格局的分布理论。

| Abstract: | Probability density function of Weibull distribution is expressed as f(x)=c/b(x-a)c-1exp(-(x-a)c/b),x≥a. The paper, for the first time, uses
the model to simulate spatial distribution of pine caterpillar population . Nine batches of sample data have been used to simulate and the results show that the spatial distribution of overwintering large larvae and overwintering pupae of pine caterpillar agrees with Weibull distribution. This research enrich the spatial distribution theory of pine caterpillar. |
