【摘要】 昆虫种群密度的二项抽样估计模型主要有两类，一类是根据空间分布型理论演绎而来，另一类是根据样方中有虫样方比例或不大于某一阈值密度T头的样方比例与平均密度的经验关系拟合的．本文综述了这两类模型、模型的变异分析、模型的理论抽样数估计等方面的研究进展．更多还原

【Abstract】 There are two categories of models for predicting insect population density by binomial sampling.The first category includes models derived from theoretical distribution formulae,and the second are those developed from empirical relationships between mean density and proportion of sample quadrats with different tally thresholds of individuals.This paper reviews the development of both categories of models and the associated methods for estimating variance of the predicted mean density and theoretical sample size.更多还原
