本文就北方地区当前的农业环境及经济条件，如何发挥现有土地资源优势搞立体农业栽培，种植的数学模型进行了初步的讨论。文中特别针对农村目前的简单种植提出了一些设想，及考虑到两种作物或３种作物套种而产生交互作用的影响，给出了二维或三维立体矩阵表示出的互惠竞争系数矩阵。对一些农业技术人员可利用计算机计算排序给出具有多种选择性的作物栽培、种植方案。并经逐年的数据积累达到指导农村种植规划的目的，以期达到更科学化。对部分半农半林的地区也可适用。
This paper discussed the current agricultural environment and economic conditions in the north, how to play the advantages of existing land resources and engage in the mathematical model of three-dimensional agriculture cultivation and planting. In this paper, some tentative ideas are put forward especially for the simple planting in rural areas, and the interaction between two crops or three kinds of crops is taken into account. The reciprocal competition coefficient matrix expressed by two-dimensional or three-dimensional matrix is given. For some agricultural technicians, computerized sequencing can give a variety of crop cultivation and planting options. And after years of data accumulation to achieve the purpose of guiding rural planting plan, with a view to achieve more scientific. The same applies to some semi-agricultural areas.
