| 摘 要： | 用6种聚集度指标对弧目大蚕蛾卵的空间分布状况进行调查与分析，结果表明：（1）该虫卵的空间分布符合负二项分布，其空间图式是聚集的，分布的基本成分是卵块的个体群；（2）最适抽样数N与平均卵密度m及允许误差D的关系为N=（I／O）。（6．6814／m）＋0．9758]。

| Abstract: | Spatial distribution patterns of Neoris haraldi eggs were investigated and analyzed with 6 kinds of aggregation indexes.Result shows that:(1) the spatial distribution of Neoris haraldi eggs,whose spatial pattern is aggregative,conforms to negative binomial distribution;the basic component of larvae distribution is individual colony;(2) the correlation of the suitable sampling value(N) with average density of eggs(m) and allowable error(D) is N =(1/D) 2(6.681 4/m) +0.975 8]. |
