摘要
本文首次运用威布尔分布于昆虫空间分布型的抽样式研究中,经推导得出符合威布尔分布型模型的理论抽样式和序贯抽样式,具体给出了惠安县马尾松毛虫种群的抽样规则,旨在为实际应用和进一步研究提供科学依据。
The Weibull distribution was first applied in the research on sam-pling formula of insect spatial distribution patterns in this paper. The theoreticalsampling formula and the sequential sampling formula in accord with Weibulldistribution model were derived and then the sampling rule for Masson's pinecaterpillar (Dendrolimus punctatus Walker) population in Huian County wasconcretely gained in order to provide a scientific basis for the actual applicationand further study.
