| 摘 要： | 应用聚集度指标法、回归分析法、零频率方法,对竹蓖舟蛾Besaia goddrica(Shaus)在竹林中的空间格局进行测定结果表明,竹篱舟蛾幼虫在竹林中的空间格局均为负二项分布,分布的基本成分为个体群;零频率方法分析表明竹篱舟蛾种群类型为“聚集度零频率制约型”,同时确定了林间调查的理论抽样数和简单序贯抽样分析表。

| Abstract: | Measured by clump intensity index, regressive analysis method and zero frequency method, the spatial pattern of Besaia goddrica (Schaus) comforted to negative binomial distribu-tion , the later, with colony as it's basis component. Jackknife estimation, the range of clump in-tensity index was provided. By zero frequency method, Besaia goddria (Schaus) population was "zero frequency dependent". The optimal sampling number of forest survey was analyzed and calculated, and calculated, and the sequential sampling analysis was presented. |
