中文摘要：

针对耕地非农转化过程中产生的一系列社会问题，采用参与性农户调查方法，对西部欠发达地区西宁市郊区5个样本村190户农户进行了随机人户调查。根据城市开发进程、到市区距离和种植类型等条件，将调查样本村分为近郊城区化农村、近郊农村和远郊农村，就农户对耕地非农转换的基本认知及耕地非农转换的经济、社会和环境价值感知进行分析。结果表明：耕地征用后农户能理性感知和判别耕地非农转换价值，并普遍认为失去耕地后生活费用增加、生活保障降低、收入来源和就业机会少；感知主要受耕地数量、区位条件、耕地开发阶段等因素的影响；处于不同区位条件的农户对耕地非农转换的价值感知存在差异性，城区化农户已逐渐适应城市生活，近郊农户的非农转换经济和社会感知压力最大，远郊农民也感知经济和生活保障压力，但更希望能通过打工增加收入。

英文摘要：

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
