| 摘 要： | 采用７种聚集度指标法测定了木兰突细蛾卵和幼虫的空间分布型。结果表明：卵和幼虫在木兰科植物人工林内部呈聚集分布，幼虫分布的基本成份是个体群，个体间相互排斥。卵分布基本成份是疏松的个体群。应用Ｉｗａｏ＇ｓ方法，分析并计算林间调查的最适抽样数，进行了幼虫序贯抽样的计算。

Studies on the Spatial Distribution Models of Gibbovalva urbana and Their Application |
| |
| Abstract: | This article adopted seven crowding level index methods to determine the spatial distributionmodels of Gibbovalva urbana eggs and larvae. The results revealed that the distribution of eggs and larvaewas a crowding one in the plantations of Magnoliaceae plants. The basic component of larva distribution wasindividual colony and the basic component of egg distribution was loose individual colony. |
