摘 要:该文分别从经济效益最大化和生态效益最大化的目标出发,以土地资源、农作物用水量、区域各类农作物需求量和农业生产直接投入为约束条件,基于线性规划方法建立武威市凉州区农业种植业结构优化的经济效益模型和生态效益模型,并对两个模型的优化结果进行对比分析,认为以草地生态农业为生产模式的生态效益模型是凉州区实现农业可持续发展较为理想的模型。Stating off from double targets of the greatest economic efficiency and the greatest ecological benefit respectively, this paper takes land resources, water consumption by crops, demands for various crops within region and direct investment for agriculture production as restrict conditions; sets up models of economic efficiency and ecological benefit with optimizing plant industry structure in Liangzhou District of Wuwei City, based on linear programming method. It carries out contrast analysis on the optimized results of these two models, and deems that the model with ecological benefit and taking pasture ecology as production model is an ideal model for realizing sustainable agriculture development in Liangzhou District.
