It has stated the development process of CVM, economic theory, pre-investigation, design of asking paper, deviation and solving ways. It selected 200 farmers and citizens of Chengdu as a sample to design the asking paper, deal with asking paper investigation and data by CVM. According to the personal information on the status of Chengdu of farmers and urban residents, investigation on cultivated land of farmer’s willingness to pay, causes of declining cognitive and service on cultivated land ecological system, the importance of farmland ecosystem service value, the protection of cultivated land, cultivated land quantity quality investigation, we know the average willingness to pay of farmers and urban residents, and then through the basic household registration information of Chengdu City w can estimate total willingness to pay land ecosystem services in the city, and on the basis of Chengdu City calculated the cultivated land eco compensation standards, through the logistic model analysis of factors influencing the willingness to pay of farmers and urban residents.
