经济、工程和生物系统之间的关系非常复杂,要想估算这三者间的函数关系是相当困难的。实践证明,数值模拟方法在评价对系统的认识程度以及验证所提出的因果关系是否正确方面是一个行之有效的研究工具。在作物栽培研究中,常用模拟方法来考察和检验作物的特性,并估算环境对该特性的作用。如果某作物具有一定的特性,可以用一模式来改进或 The relationship between economy, engineering and biological systems is so complex that it is quite difficult to estimate the functional relationships among the three. Practice has proved that the numerical simulation method is an effective research tool in evaluating the degree of understanding of the system and verifying whether the proposed causal relationship is correct. In crop cultivation research, simulation methods are often used to examine and test the characteristics of crops and to assess the effects of the environment on this trait. If a crop has certain characteristics, a pattern can be used to improve or
