害虫防治决策的复序贯分析方法及抽样技术研究

Composite sequential analysis methods and sampling technique in the strategic decision of insect pest control.

复序贯抽样决策技术实际应用的受限 ,原因在于截止限序贯抽样模型的缺乏。本文在检验昆虫种群空间格局回归模型的基础上 ,推导出了目前国内常用检验回归模型的截止限序贯抽样模型 ,并将其运用于复序贯分析决策过程中。实例分析表明 ,对于同一种生物种群 ,在一定的精度 (D)和置信水平(tα)要求下 。

Based on the examination of the regression model of insect population spatial patterns,the out\|off limited sampling model for examining the commonly\|used regression model in China was deduced,and applied in the course of composite sequential analysis strategic decision.The analysis on an example showed that the composite sequential sampling using this model for control strategic decision had the great advantage of saving sampling expense in certain requirements of the precision and confident level to the same population.
