五、作物布局当前,系统工程的原理与方法更加深入地应用于农业,它不但为大农业战略思想提供了科学依据,而且为大农业系统综合研究提供了有力的现代化工具。在农业系统工程中,最优方案选择的途径是多种多样的,其中线性规划的方法是常见的一种。应用线性规划进行作物布局的优化分析,在我国已有研究,并已显示出其生命力。农作物的布局问题,实际上是人们根据农业大系统 V. Crop Layout At present, the principles and methods of system engineering are applied to agriculture more deeply. It not only provides a scientific basis for the strategy of large-scale agriculture, but also provides a powerful modern tool for the comprehensive study of large-scale agricultural systems. In agricultural systems engineering, the optimal choice of approach is varied, of which the linear programming method is a common one. The optimization analysis of crop layout using linear programming has been studied in our country and has shown its vitality. The issue of crop layout is actually based on large agricultural systems
