摘要
机械化农业生产系统具有耗散结构特征,其开放性、非平衡性以及非线性作用机制和涨落机制决定了系统的发展和演化过程;要直接建立其演化模型是非常困难的。根据建立的系统动力学模型,分析了系统的演化特点,最后提出了实现系统合理演化的有应用价值的结论。
Mechanized agricultural production system having the dissipation structure characteristics,its opening characteristics,non-balance characteristics,non-linear opera- tion mechanism,rise and fall mechanism decide the development and evolution processes of the system.It is difficult of establishing evolution model directly.According to the system dynamic model,system evolution characteristics are analyzed.At last a valuable conclusion to achieve rational evolution of system is pointed out.
