粮食作物生产机械化系统动力学建模与仿真

SD Model and Simulation of Grain Crop Mechanization Production

摘要:

分析了中国粮食作物机械化生产系统结构组成，构建了因果分析图和系统动力学流图。在此基础上，进行了系统动力学模型构建与仿真分析。结果表明：经济发展水平、土地经营规模、农业劳动力转移是影响粮食作物机械化生产系统的主要因素。只有通过提高粮食作物生产规模化程度和专业化程度并配合产业发展规律，才能从根本上提高机械化生产的效率和生产能力。

Abstract:

The Chinese grain crop mechanization production system structure was analyzed. A causal analysis diagram and flow chart of system dynamics were constructed. The results show that, the proportion of capital investment, land management scale and equipment level were the main factors effect of grain crop mechanization production system. Only by improving grain crop production scale of the degree of specialization and the law of industrial development, the mechanization production efficiency and production capacity would improve. 
