Abstract: Comprehensive benefit evaluation of returning farmland to forest is an important basis for the continuous progress of the project. Based on the status of returning farmland to forest in the loess plateau of northern Shaanxi and Guanzhong plain from 2000 to 2015, the analytical hierarchy process and the multiplication and integration method were applied to quantitative analysis of returning farmland to forest in terms of ecological benefits, socioeconomic benefits and policy responses. The trend of comprehensive benefits from returning farmland to forest in northern Shaanxi and Guanzhong was basically the same, a steady upward one. Since 2008, the benefit value was positive. From 2000 to 2005, the value of benefits rose year by year, dropped slightly in 2006, then the benefits increased significantly. The maximum value appeared in 2012, which was 0.2669 and 0.2008 in northern Shaanxi and Guangzhong, respectively, and the achievement of returning farmland to forest has gradually emerged.
