摘要
本文将Holling圆盘方程线性化后,运用线性化中的加权处理办法,提出了圆盘方程参数估计的误差加权方法。通过实例验证,本方法具有拟合精度高、计算量小、计算并不复杂、便于应用等优点,同时可与Gauss-Newton及Marquardt迭代法的拟合精度相近,由此,可为建立天敌——害虫作用系统的量化关系提供一种新的研究办法。
This paper put forward the weighted method for error of disk equation's parameters estimation, applying the weighted method for linearization after the Ho-lling disk equation had heen linearized. Tested and uerified by living examples, shaw that its precise degree is equal to that of Gauss-Newton and Marquardt's step by Step Method. its estimation is ncomplicated and simple in use. Thus, can provide an objective method for setting up the Predator-pray Systems.
