摘　　要：以涌禾有机农业基地为例,通过对系统环境的辩识,系统动力学中关键顶点赋权图模型、最优化技术中多项式线性模型的构建与结合使用,建立起一种以系统养分平衡为依据的生态种养共生模式,采用切诺斯综合方法对模式进行评价与选优。并提出了与之相匹配的4×4=16个技术单元组成的全集U的系统集成方案。An ecological symbiosis model between planting and stoekbreeding was established based on nutrients balance within the system of Yonghe organic agriculture base, by using both key vertex weighted diagram model of system dynamics and polynomial linear model of optimization technique. The Chenowth ~s comprehensive assessment system was applied for assessing and priority choosing. Accordingly,one system integration technology with an universal set composed of 16 technique units was provided for the model.
