Abstract:: In order to further research the inner drive coupling mechanism of agricultural eco-economic system, the drive force is analyzed by using the statistical date of Wuqi county (1990, 1999-2006) and principal components analysis method. The results showed that the human economy development factor is the main driving force of agricultural eco-economic system evolution (contribution rate is 72.849 9%) and the population pressure is the second driving factor (contribution rate is 11.569 5%). The factor of natural ecological environment is the basis of coupling process of agricultural eco-economic system in Wuqi county (contribution rate is 8.168 1%). Aiming at the internal driving mechanism and its facing problem of agricultural eco-economic system. The county need to adjust the industrial structure, develop grass industry to ensure the stability of the agricultural eco-economic system.
