摘　　要：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。In this paper,linear combinatorial method is used to establish the matter flow model of the mixed agri-ecosystem and the unlinear models are used in subsystems.Some patterns of different management(such as cropping system,manuring and so on )of the system in Harbin are run for 20 year.According to the results the sustainability,management and decision of the system are analyzed.The results show that we must carry out the agricultural developing patterns of proper integration of organic and inorganic fertilizer,mixed croplivestock in order to realize the system sustainable developing.
