摘　　要：Scale pig production is an effective approach to improve farmers＇ income. Many pig feeding villages and intensive pig farms has presented rapidly in Center China in recent years, the focus of large quantity of manure and sewage discharged by pig farms has become the leading source of pollution in vast rural areas. How to dissolve the contravention between the development of scale pig production and the serious pollution caused by swine excreta in rural area is a complex systematic problem. An approach named Systems Dynamic Digraph Analysis Approach is presented in this paper. And the approach is applied to analyze the scale pig breeding system in small hill watershed area systematically. A case of Pingxiang Taihua pig farm in the west region of Jinggang Mountain, which is a typical intensive pig farm in small hill watershed area in Center China, was studied, after the systematical analyses with its system dynamic digraph, three common management policies are presented at the end of the paper.
