本文应用线性规划的方法,以南方水田地区一个典型生产大队为研究对象,就农业生产中,如何合理利用现有土地、劳力、机械、畜力等资源为限制因素,在保证满足国家、个人、集体三者对农产品需求的前提下,求得农业生产作物布局的最优化,以达到最低能源消耗或最大纯收益的目标。所建立的数学模型,经电子计算机运算,求得之各种方案可对生产单位的资源利用,能源消耗,经济收益作出定量的分析对比,以便作出符合实际的作物布局的最优决策,同时可检验农业生产单位现行作物布局的合理性。
This paper applies the method of linear programming to take a typical production unit in the paddy field of southern China as the research object. In the agricultural production, how to make rational use of the existing resources such as land, labor, machinery and animal husbandry as the limiting factors and ensure that the national, individual and collective The three agricultural products under the premise of the demand for the optimization of the layout of agricultural crops in order to achieve the lowest energy consumption or maximum net income target. The mathematical model established by the computer operation, the various programs obtained by the production unit of resource use, energy consumption, economic returns to make a quantitative analysis and comparison in order to make the optimal crop layout in line with the actual decision-making, at the same time Test the rationality of the current crop layout in agricultural production units.
