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。在检验害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 ,复序贯抽样决策方法可以大幅度地节约抽样成本。 The limited practical application of complex sequential sampling decision-making techniques is due to the lack of a cut-off sequential sampling model. Based on the regression model of pest population spatial patterns, a cut-off sequential sampling model of the commonly used regression model in China was derived and applied to the process of complex sequential analysis and decision-making. The case study shows that for the same kind of biological population, the complex sequential sampling decision method can significantly reduce the sampling cost under certain accuracy (D) and confidence level (tα).
