摘要
该文采用了6种聚集度指标,2种回归模型对可可广翅蜡蝉成虫在茶园的空间分布型进行了探讨,结果表明均属聚集分布,聚集原因是由其本身的聚集行为与环境因子综合影响的结果.同时探讨了Iwao理论抽样模型及Willson序贯抽样技术,从而确定了在不同虫口密度下的理论抽样数及不同抽样点数下的累积虫口量.
Six aggregation index methods and two regression models have been used to analyze the spatial distribution of icania cacaonias adult in this article. The results showed that its spatial distribution in the tea garden has been estimated to be of aggregated type, and the comprehensive influences of its aggregated behaviors and environmental factors led to the result. Meanwhile, Iwao theory sampling model, Willson sequential sampling technique have been discussed, thus the theoretical sampling number depends on difderent population densities and the cumulative population quantity on different sampling points have been determined.
