本文对榆跳象幼虫进行了林间分布型和抽样技术的探讨,结果表明榆跳象幼虫属聚集型的核心分布,亦属二项分布。林间调查以平行线取样法精度最高,并利用样本方差和允许误差限建立了序贯抽样表。
In this paper, we studied the spatial distribution and sampling techniques of the larvae of P. elegans. The results showed that the distribution of larvae of P. elmiana was also a binomial distribution. The inter-bank survey with the parallel line sampling method has the highest accuracy, and established the sequential sampling table using the sample variance and the allowable error limit.
