摘要
本文是从实现人体营养均衡,满足健康需要的条件下,利用Spss软件筛选出主要的水果和蔬菜,对果蔬消费和供给建立食饵—捕食者模型,并对这个模型做微分方程定性理论分析和MATLAB数值预测。给出到2020年我国果蔬生产的战略调整建议。
Under the conditions of achieving the human balanced nutrition and meeting the need of health, this article uses Spss software to filter out the main fruits and vegetables, establishes a prey-pre- dator model for the consumption and supply of fruits and vegetables, does the analysis of the qua-litative theory of ordinary differential equation and MATLAB numerical prediction with the model, and gives the strategic adjustment about fruits and vegetables production of China in 2020.
