With continuous urbanization，China reached the Lewis turning point around 2003.Thereafter，the rapid rise of non-agricultural wages led to an increase in the cost of agricultural opportunities，which in turn transmitted to agricultural labor prices，resulting in a decrease in net income from farmland cultivation.Because of the significant differences in natural conditions，adjusted farming practices vary between farmers in mountainous and plain areas.Such differences result into different labor costs，agricultural labor productivity，and net profit（rent），and subsequently to different changes in land-use types.Types of farmland marginalization include farmland abandonment and farmland to orchard and woodland；both favor revegetation and reforestation.Therefore，this dataset first analyzed the input and output changes of farmland cultivation in mountainous areas after the Lewis turning point by comparison with plain areas，which demonstrates the economic characteristics of farmland marginalization.Then，farmland and forest area of mountainous regions before and after the Lewis turning point were calculated to reveal the land-use change.
