近些年，随着城市化脚步的加快，城区不断向外围扩张，城市周边的近郊地区不断被纳入城区范围之内，伴随而来的是大规模的征地拆迁运动。因其发展之迅速，规模之庞大，这一运动受到了社会及学术界的广泛关注。相关的研究不仅涉及到拆迁征地运动本身，而且对被征地、被拆迁的当事人也给予了相当多的关注，失地农民问题也由此为社会所熟知。本文认为在征地拆迁过程中，失地农民在一定程度上产生了信任危机，包括对人的信任危机和对系统的信任危机。本文以内蒙古西部某村（以下简称“西村”）为例，以该村村民为调查对象，从 2011年12月到2012年2月底在该村进行了访谈。通过对访谈资料的整理和分析，首先论证失地农民在征地拆迁过程中是否产生了信任危机，以及危机的程度和表现，并对信任危机产生的原因及信任重建的方式方法进行了探索性研究。研究结果显示，促使失地农民产生信任危机的原因是多样的。征地后社会保障制度缺失、征地拆迁中可获得的相关信息透明度低，征地补偿情况不理想，补偿政策执行不力，失地农民自身的个人因素等等都是信任危机产生的重要诱因。此外，研究显示，不同年龄段的失地农民，信任危机的程度存在显著的差异。征地拆迁后的社会保障对信任重建产生重要影响。

In recent years, along with the expansion of urbanization, suburban areas are continuously contained in the range of city, accompanied by large-scale requisition and relocation. Because of its rapid development and large scale, close attention this is being paid to the movement by the society and the academic circles. Related reseaThe results show that the causes of trust crisis of landless peasants are diverse. After the land requisition, unperfect system of social security, lack of available information, low diaphaneity and unreasonable compensation of land, ineffective compensation policy implementation, landless peasants' own personal factors are important causes of trust crisis. In addition, studies show, different ages of landless peasants, trust crisis level has significant difference. The social rches involve not only the movement itself, but also on the persons whose land is requisitioned, so the problem of landless peasants is also known by the society. This paper argues that in the process of land expropriation, landless peasants experience a trust crisis to some extent, including the crisis of confidence in persons and in systems.This paper takes a village in west Inner Mongolia as an example and the villagers as the research objects, from December 2011 to the end of February 2012 , I had some interviews at the villager. Based on the collation and analysis of these data, this paper answers the question whether the landless peasants experience a trust crisis in the process of land expropriation, then argues the degree, the manifestation and the causes of the trust crisis. In the final part, give some suggestions on the reconstruction of trust.security after land requisition demolition has important effect on the reconstruction of trust.
