Returning Farmland to Forests main purpose is to improve the ecological environment, natural disaster reduction, to achieve the sustainable development of man and society. Grain for Green Project in Tibet Qamdo in Tibet in 2002 to start a pilot implementation in full swing in the Tibet Autonomous Region in 2003. The implementation of the project the effectiveness of how in the past few years, the focus of attention of the majority of farmers and herdsmen fanners. Therefore, the analysis of the benefits generated by the Grain for Green Project has important practical significance. Select namling County of the Tibet Autonomous Region as an object of study, public goods theory and the theory of economic growth in the access to large amounts of literature and field investigations on the basis of the establishment of evaluation index system, use of effective monitoring farmland in the region also the forest projects benefit analysis, and recommendations suitable for sustainable development in Tibet, according to the theory of sustainable development. Firstly, set up according to the evaluation index system principle, drawing on existing research results, the use of theoretical analysis and field survey to establish the ecological, economic and social benefits evaluation index system; Secondly, according to the established evaluation shadow project and statistical analysis methods (paired data significance test, regression analysis, before and after contrast) evaluate the ecological, economic and social benefits of namling County Grain for Green Project; Finally, according to the above studies, and proposed the corresponding recommendations. Ecological benefits: Returning Farmland to Forests and restore forest vegetation, vegetation coverage, the forest coverage namling County increased from 8.69% in 2002 to 8.98% in 2010; protection of water resources value 13,354,300 yuan ; cleaning up the environment value of 6.2643 million yuan; effectively increase the oxygen content of air, the oxygen content of the namling County increased from 56% to 50% of the oxygen content of the Mainland, and release oxygen into the value of 1,934,600 yuan; protect farmers animal husbandry value of 5.4656 million yuan; Soil and Water Conservation value of 57.6738 million yuan. The total value of the ecological benefits of 84.6926 million yuan. Economic benefits: the implementation of the Grain for Green Project, the The project area fanners income increased total grain production and animal husbandry stable income, expanding forest products acreage; income structure of rural economic change: gradually reduce the proportion of grain and livestock income a small proportion of the forest products revenue gradually increase; optimization of land use structure, limited land underutilized; using CES production function model to measure the Grain for Green Project on economic growth elasticity of substitution of 0.0256. Social benefits: the implementation of the Grain for Green Project, through the wide Indian Bilingual leaflets effectively enhance the enthusiasm of farmers and herdsmen in the masses to participate in support of returning farmland to forests and engineering areas returning farmland to forest, and indirectly improve their Chinese level of understanding; enrollment rate has increased year by year, the enrollment rate is the multifaceted impact of factors, not necessarily linked with the returning farmland to forests, farmland subsidies increase the income of fanners, which will indirectly affect enrollment rate; At the same time, the liberation of the productive forces, promote the transfer surplus labor by the original labor migrant to increase their income. Implementation of the Grain for Green Project in Tibet, improve the ecological environment in Tibet, to protect the fragile plateau ecology; Abandoned farm household's income, promote economic growth and social stability and unity of the county, has made significant economic and social benefits. In order to consolidate the achievements of the Grain for Green Project, proposed to increase state aid to Tibet investment to support infrastructure construction; vigorously develop follow-up industries; improve the scientific quality of the local farmers and herdsmen; further improve the ecological compensation mechanism, improve farmland also forest project effectiveness.
