针对Lotka-Volterra生态系统模型中的高精度参数如何确定问题，本文通过对长期积累的观测数据进行分析，提出先对误差数据进行卡尔曼滤波器将噪声滤除，然后利用最小二乘曲线进行拟合，以确定模型中的参数在最小二乘曲线意义下的最优解，最后利用M atlab和M aple计算机软件进行了模拟仿真，结果表明该方法对高精度参数确定问题有一定的有效性。

Determining the high accuracy parameters of the Lotka -Volterra ecosystem models is a wor-thy research .Based on the long -term accumulation of analyzing observation data ,an approaching of Kalman Filter was proposed for noise filtering to error data in this paper ,then a least -squares curve fitting was used to determine the optimal solution of model parameters ,finally a simulation was tested by using the Matlab and Maple software .The result shows that the presented approach of determining high accuracy parameters has a certain effect .
