| 摘 要： | 本文根据函数Taylor展开式,以二次多项式建立数学模型讨论白背飞虱各龄个体被捕食量与捕食性天敌间的数量关系。应用二次通用旋转回归组合设计法辨识模型参数,据所得模型,组建捕食性天敌对白背飞虱控制矩阵。为白背飞虱种群优化控制提供基础材料。

| Abstract: | Based on the Taylor expansion,the quadratic function was applied for theanalysis of the numerical relationship between the numbers of white-backplanthopper(Sogatella furcifera)attacked and the densities of predators.Theparameters of this model were identified by the rotation composite design ofquadratic regression.Based on the models,the control matrix of the predators onthe various stages of this pest was constructed,and used for its optimal control. |
