Abstract:: In order to provide a scientific theoretical basis for further promoting the implementation of the project, the ecological and economic benefits of returning farmlands to forests in Chongqing City were studied. Chongqing City in the southwest was taken as a research area. The ecology and economic aspects were analyzed and discussed based on the monitoring data related to returning farmlands to forests, Chongqing historical yearbook data and past year environmental status bulletins, and field-involved household surveys. The following results have been obtained. The project not only significantly improved vegetation coverage, but also played the positive role in soil and water conservation, improving soil quality, purifying the atmosphere and sequestrating carbon and releasing oxygen. At the same time, the ecological forest is the main type of forest in the project of returning farmlands to forests, but the growth potentials and coverage of the economic forests are better than the ecological forests as a whole. The proportion of the mixed forest of arbor and shrub is extremely low; after returning farmland to forest, the area of cultivated land reduced, but the grain output gradually returns to the original level. Per capita income has increased significantly, with an average annual growth rate of 31.9%. Meanwhile, the output value of forestry is also increasing year by year. The implementation of returning farmlands to forests will promote the ecological environment and local economy. However, the proportion of mixed forests of arbor and shrubs should be further increased, and the management and protection of ecological forests should be strengthened. In addition, effective measures should be taken to increase the output value of forestry.
