Abstract: Some social contradictions are aroused from the rural-urban conversion of farmland. Farmers lost land and have to adapt to the new way of life. So it is important to find the root problem from the view of the farmers. The Participatory Rural Appraisal is a good method to know the farmers' living condition and was applied to this study in the rural area around Xining city, Qinghai, China. Five sample villages were selected based on development period divided into three groups: urbanized village with location adjacent to urban, suburban and out suburban areas. The former two groups belong to early suburban development zone involving four villages. The latter group is recent outer suburban development zone involving one village. There are altogether 190 farmer households in five sample villages. We investigated them randomly. By analyzing the basic understanding and perception on economic value, social value and environmental value of farmland rural-urban conversion, this paper attempts to find the deep root of social problems and to put forward some advice for the regional land use and sustainable development. The results show that: the farmers' perceptions on non-agricultural conversion are mainly affected by per capita farmland, land development, distance from city. Their perceptions are basically consistent with the reality, which can be explained reasonably. Therefore, landless farmers make decisions rationally and know value of farmland urban-rural conversion. After expropriation, farmers generally have perceptions of increasing living cost, insufficient living guarantee and old-age security, and decreasing employment and income. The expansion of built-up lands and the improvement of infrastructures are decreasing transportation cost and pushing land price up. The farmers' value perception of farmland rural-urban conversion varies with location condition and with the biggest pressure perceived in the suburban areas. Urbanized farmers have the highest social value perception on rural-urban conversion due to the fact that earlier expropriation makes them get used to city life; suburban farmers' perceptions on that concentrate on increasing living cost, weakening living guarantee and land appreciation, because they are geographically oppressed by city and country; Out suburban farmers are eager to become citizens and hope to increase income by working in cities.
