To provide scientific guidance of a new round of the implementation of returning farmland to forestland and grassland in arid desert area of northwest China, Turpan City was selected as study area, a comprehensive benefit evaluation index system was established based on 15 indicators which represented the characteristics of the region. The index weights were determined based on combination of cloud model and the variation coefficient method, the method of proportion method was used to make index data dimensionless, the additive synthesis method was used to evaluate and analyze the comprehensive benefit of farmland conversion project, and the ecological benefit, economic benefit, social benefit and policy response index were predicted by grey system prediction model GM(1,1)from 2021 to 2025. The results showed that:(1)from 2004 to 2019, the comprehensive benefit index increased year by year, and the new round of farmland conversion increased two times as much as the previous round;(2)the increase of forest coverage rate, the expansion of soil erosion control area, the increase of rural per capita net income and the increase of the total output value of forestry industry were the main factors contributing to the improvement of ecological and economic benefits;(3)the implementation of the project promoted the positive development trend of industrial structure and employment structure; the improvement of the farmers' willingness to return to farmland consolidated the achievements and made them have a long-term effect;(4)from 2021 to 2025, the predicted values of ecological benefit, economic benefit, social benefit and policy response index showed an upward trend with the order of economic benefit index>policy response index>ecological benefit index>social benefit index. According to the prediction results, ecological construction should be the key point in the implementation of the new round of farmland conversion projects in the arid desert areas of northwest China, the effective connection between ecological compensation and rural revitalization strategies should be strengthened, the citizenization of the migrant agricultural population should be promoted, in order to realize the coordinated development among ecological, economic, social and policy responses.
