用数学模型方法来研究种植业生产系统,可以对农田产量与其影响因素之间的复杂相互关系进行定量的概括,揭示其本质的内在联系。为了对黄淮海平原农业发展战略研究提供科学依据,我们选择该地区的中低产典型县—山东省陵县为研究对象,运用电子计算机对历年农田产量与多种影响因素的相关性,进行定量分析,找出促进或限制产量的主导因素,建立了农田产量综合数学模型。现将我们初步探索的研究方法及结果介绍如下。
To study crop production system by using mathematical model method can quantitatively generalize the complicated interrelationship between crop yield and its influencing factors and reveal its intrinsic relationship. In order to provide a scientific basis for the research on the strategy of agricultural development in the Huang-Huai-Hai Plain, we chose the typical low- middle-yielding county in this area, Ling County, Shandong Province, as the research object, and used the computer to quantitatively analyze the correlation between crop yield and various influencing factors , Find out the dominant factor to promote or limit the yield, and establish a comprehensive mathematical model of farmland output. Now we initially explore the research methods and results are as follows.
