对春尺蠖( Apocheima cinerarius Erschoff )卵块空间分布格局进行测定，应用平均拥挤度指标、扩散指数等5种聚集度指标以及Iwao 等2种回归模型法对春尺蠖卵块的空间分布型进行分析和检验，并根据Iwao模型参数建立春尺蠖卵块的理论抽样数模型及防治界限。结果表明：春尺蠖卵块在罗山柠条林呈聚集分布特征，分布的基本单位是个体群。引起聚集的原因主要是春尺蠖的自身习性，与环境因素也有一定关系。

The egg-mass spatial distribution of Apocheima cinerarius Erschoff in Caragana korshinski was analyzed in 7 indexes by methods of Iwao's regression analysis and Taylor power principle etc.. The results showed that the spatial distribution pattern was aggregated distribution in Luoshan Mountain, with a group of individuals as a unit. More egg-mass were found in the eastern, western and northern sectors of Caragana korshinski trees than in the southern sectors. The aggregation of the populations of this insect was due to their food habit, behavior and some environmental factors. In addition,the optimum theoretical sampling model and control boundary were calculated by Iwao's method.
