Abstract Faced to the actual situation of Ya'an City,eco-economic evaluation system has been established in this region,and eco-economic condition has been evaluated through the methods of AHP to the three counties,that is Yucheng,Mingshan and Hanyuan.The results shows that Yucheng's ecology benefit index is 0.216 0,the economic efficiency index is 0.433 2,the social efficiency index is 0.047 4,the eco-economy synthesis benefit index is 1.345 7,the composite index is obviously higher than those of Mingshan and Hanyuan;The difference of the eco-economy synthesis benefit index is not obvious between Mingshan and Hanyuan,but in various sub-items index ther are some differences,for example,Mingshan's social efficiency index is better than that of Hanyuan,but Hanyuan's ecology index is better than that of Mingshan.The study may provide the certain theory basis for the decision-making body,and to promote the counties to realize the sustainable development.
