摘要
本文就昆虫种群简单随机抽样技术中最适样方大小的确定方法作了较为系统的总结,它们是:①按Iwao m-m模型确定最适样方大小;②按改进的Iwao m-m模型确定最适样方大小;③按再次改进的Iwaom-m模型确定最适样方大小;④按m-m幂法则确定最适佯方大小;⑤按Taylor幂法则确定最适样方大小;⑥按负二项分布参数k确定最适样方大小;⑦按Morisita Iδ指数确定最适样方大小.对这些方法均用实例进行了验证.同时,文中还提出了一些新的模型和方法.
In this paper, methods of optimum plot size determination in the simple random sampling of insect population are summarized sysmatically. The methods arc: Iwao m*-m model, improved Iwao m*-m model, further improved m*-m model, law of m*-m function, law of Taylor function, parameter k in negative binomial distribution and index Iδ of Morisita. And these methods are all verified with real examples. Besides, further models and methods are put forward in the paper.
