Urbanization is the trend of social development today, and the traditional model of providing for the aged depending on the land are challenged tremendously. Land expropriated induces directly that the aged lose the life base, the middle aged lose their emplyment oppertunity, and the minors lose the possible rights of employmert and their earning. The three problems will affect the social insurance of the aged in rural area directly or indirectly. Based on the survey about the land-expropriated farmers in Zibo, this paper shows that the three problems are the most important problems for the farmers after land expropriated, and that the keys points of solving the problems are to perfect the institutions of land expropriation, to supervise the utilization of compensations more strictly, and to diversify the measures of compensations for land expropriation.
