Abstract: On the basis of investigation and analysis of Yingjing county agricultural resource and actuality evaluation, a system dynamic model about the optimization adjustment of agricultural production structure of Yingjing county is established with system dynamic theory, and a dynamic simulation for the Yingjing agricultural production structure adjustment has been done on the computer. By means of changing control variables and adjusting parameters, the paper seeks the better scheme of structure adjustment, and makes a macro-forecast for the future system, structure and development, thereby provides theoretical and experimental advice for the policy-making for the adjustment of agricultural structure of Yingjing county, on the basis of the overall aim for the development and control of the system, to be specific, the proper and effective utilization of the system, resources, the better harmony of industry internal structure, the good development of the system economic and social benefits, and the better ecological environment.

Key words: agricultural production structure, system dynamic model, optimization adjustment, mountain areas around the Sichuan basin
