摘要
本文对昆虫种群抽样技术的研究内容、抽样理论作了概述。关于种群的估值抽样技术分别就其抽取方法与数据统计分析、样本单元的选择、理论抽样数的确定、以及种群密度的简易估计方法等方面的研究现状作了介绍。关于种群序贯抽样以及利用序贯抽样方法估计种群密度等问题也进行了总结、评述。
In this summa, the state-of-the-art in sampling technique of insect populations are reviewed. The theory and practice of the sampling technique for insect populations were summarised, On sampling for estimating population abundance, the sampling scheme and data analysis, selection of sample unit, calculation of optimum sample size and simplified estimation method (estimating population defisity from relationship between zeroquardt frequence & population density) were reviewed respectively. Also the Risk Decision Sampling (Sequential Sampling) and Simpli-fied Sequential sampling (Presence-Absence Sequential Sampling) were approached.
