摘要
本文采用聚集度指标法和回归分析法,测定了锥栗珊毒蛾Lymantria viola Swinhoe幼虫在防治前后的空间分布型;研究结果表明,锥栗珊毒蛾幼虫在防治前后在林间分布基本成份是个体群,空间分布型均为聚集分布,文中分析并计算了林间调查的最适抽样数,列出序贯抽样分析表。
The spatial distribution patterns of Lymantria viola Swinhoe was measured by using aggregate index and relative coefficient method. The results showed that the spatial distribution pattern of Lymantria viola Swinhoe is aggregate, the basic composition of distribution is the indi-vidual group.
