Holling圆盘方程参数估计方法的研究

Method for Estimating Parameters of Holling Disk Equation

本文直接对Holling圆盘方程用最小二乘法,提出一种新的拟合方法——加权最小二乘法,并由此得到了Holling圆盘方程参数T_h,a′的估计式。比较结果表明:加权最小二乘法拟合结果较好,且拟合效果稳定,方便实用。

The present paper proposed a new fitting method, weighted least square method, for estimat-ing parameters of Holling disk equation and the formula for estimating the parameters were ob-tained in the form of: Comparing results showed that the fitting results of the weighted least square method wasbetter than those of other methods, with good stability and easiness.
