At present, with the rapid development of breeding enterprises in our country and the continuous improvement of large-scale breeding enterprises. The amount of pollution produced by large-scale farming is increasing rapidly and relatively concentrated, resulting in increasingly prominent environmental pollution problems. Aiming at the environmental pollution problem of large-scale farming enterprises,the dynamic model of the environmental behavior system of large-scale farming enterprises by using the basic flow rate tree modeling method was firstly established, and then the minimal feedback schema step by step by step by using the minimal feedback schema generation method was obtained. Finally, on the basis of the minimal feedback schema, a feedback schema of the growth ceiling with practical significance was constructed. Finally, some practical suggestions are put forward to enhance the environmental behavior of enterprises.
