| 摘 要： | 对安徽沿江棉田棉铃虫卵的空间分布动态规律进行了调查研究，结果表明棉铃虫卵在棉田的聚集程度随发生代次而逐渐增强，发现不同代次虫口密度相同对理论抽样数明显不同，提出了沿江各代估值调查中的理论抽样数，并对几种空间格局模型拟合棉铃虫的空间分布情况作了比较。 |

| Abstract: | The dynamics of spatial pattern of Helicoverpa ar migera egg s in cotton fields in Yanjiang were studied. The results showed that:the aggreg ation would increase when the generation of cotton bollworm went on; sampling nu mber of cotton plants were obviously different when the densities of the populat ion of different generations were equal and the reasonable sampling number was g iven; different models of spatial pattern were compared. |
