摘要
应用空间分布型统计参数Iwaom-m模型中α、β及若干聚集度指标分析了烟蚜在晒红烟烟田的空间格局,并对抽样技术进行了探讨。结果表明:烟蚜空间格局为聚集型,依此提出了估算烟蚜在不同密度下的理论抽样数。
The spatial pattern of Myzua persicae （Sulzer） in tobacco field was analyzed with the α,β and some indexes of social degree in Iwao m^＊ - m model of statistical parameter of spatial distribution, and the sampling technique was discussed as well. The results showed that the spatial pattern of Myzus persicae （Sulzer） in tobacco filed was social. Based on that, the theoretical number of sampling for numerical estimation of Myzus persicae （Sulzer） at different population density was put forward.
