Abstract: At present, China is entering into a rapid development stage of urbanization. The urbanization process accelerates the scale and rate of non-agriculturization of agricultural land. Meanwhile, it brings a series of social problems, which are represented by land expropriation. These problems included broad land expropriation scale, abnormal expropriation compensation, single settling pattern for land-lost farmers, and nontransparent land expropriation process. Based on analysis of the problems in the land expropriation system, the corresponding measures are put forward in four respects, including limiting scope of land expropriation, establishing compensation standard of land expropriation, settling land-lost farmers and improving system and process of land expropriation.
