摘 要: | 文章主要研究确定生态系统模型中高精度参数的问题。首先利用给出的观测数据的周期性,先对有误差的数据进行去噪预处理,然后建立了以仿真值和观测值的方差为目标的选优模型,利用计算机进行了搜索和仿真找出最优解。结果表明该模型能够有效地解决高精度参数估计中消除测量数据误差的问题。

Abstract: | Determining the highaccuracy parameters in ecosystem model is studied.Using the periodicity of the observational data, we has the data to carry on the denoising pretreatment firstly, and then set up a optimization model for the objective of the variance of simulation values and observed values, and use computer simulation and a search to find the optimal solution. The results show that this model can effectively slove the problem that we remove the measurement data error in the high-accuracy parameters estimation. |
