Referring to the data of statistical yearbooks and peasant household questionnaires,the effects ofecological agriculture with commodity（EAC）implemented in southern,central,northern An′sai Countywere evaluated by using the evaluating indicator system and the weights.Results showed that in last 10years,the EAC in An′sai County experienced 3stages:economic system recession and ecosystem smooth transition stage,economic system recovery and ecosystem rapid development stage,and economic systemquick growth and ecosystem sound wave stage.The EAC development state was in the“fair”grade in 1998-2001,which evolved into the“good”grade in 2002-2009and is expected to achieve the“superior”grade by2015.During this process,the EAC system tended to be a coordinated development state,but there were also some uncoordinated problems in parts,such as resource-shortage in livestock husbandry and resourcewaste in vegetation,which constrains the EAC advancement in An′sai County.
