英文摘要： After systematic study of the connotation of the design of circular agricultural pattern, this project proposed a framework consisting of target system, concept settings, system boundary, system structure, system optimization, operation mechanism and dynamic evaluation. Under the system framework and with the application of SD (system dynamics) theory to the system engineering of 'scale breeding and planting' and 'ecological energy', a multi-objective planning model was built for planting pattern optimization of circular agriculture. Based on regional material-flow and co-flow, this project discussed the modeling method combining SD model and structure model and studied the eco-chains' connection and transformation of circular agricultural patterns. A dominant structure model was constructed for ecological carrying capacity and the optimized scheme was brought forward through system simulation and scenario analysis. The model of agricultural technological exchange was established and the exchange patterns of circular agricultural production technology were explored. The study was also conducted on the systematic operation mechanism of the circular agricultural patterns headed by scale breeding. The SD model of dynamic evaluation was then generated for circular agriculture based on SD principles and methods, and was applied to dynamic evaluation of circular agricultural patterns in hilly areas. On the basis of the previous researches, this project constructed an experimental platform of system simulation for the design of circular agricultural patterns.These theories and methods and their application not only enriched the theories of designing circular agricultural patterns but also proved rather applicable to low carbon and ecological energy system engineering On the research and teaching base of Nanchang University. This project provided theoretical reference for creating typical circular agricultural patterns centered on culturing farm and contributed to make the designed patterns the model for Jiangxi Province and Ministry of Agriculture in circular agriculture of scale breeding.
