采用子系统用非线性模型、大系统线性整合的方法建立了农牧生态系统物流模型，并进行了哈尔滨地区农牧系统不同种植制度、培肥等管理方式的各种农牧结合模式２０年演示。根据演示结果进行可持续分析和管理决策分析，说明要实现系统持续发展必须实施适宜的有机无机相结合、农牧结合的农业发展模式。
The subsystem of agriculture and animal husbandry was modeled by the nonlinear model of the subsystem and the linear integration of the large-scale system. The 20-year demonstration of various agricultural and animal husbandry combined modes of different farming systems and fertilizations in farming and pastoral system in Harbin area was carried out . Based on the results of the demonstration, the sustainable analysis and management decision-making analysis are carried out to show that in order to achieve the sustainable development of the system, proper combination of organic and inorganic agriculture and agriculture and animal husbandry should be implemented.
