Land Acquisition Process, The Social Security Of Landless Peasants Land Value Estimates

With the development of our economy, the needs of building land become more and more. This also lead more and more lands are expropriated. In this process, many farms are compelled to leave the land. But this people can't find job, because of less skills to make a living. However the aftercare and live security of this people aren't enough to ensure people's live.Because of this, my paper begins from aftercare and compensation fare, and define it as society security value of land. Then analyse why land have society security value. At the same time, I analyse land's four forms of society security value, such as security value for aged people,security value for medical treatment,out of work people and the least live fees. It set base for latter chapters.After that I analyse land's security function, study limitation of means about estimating price of land's security. And through appraise,analyse and assimilate the merits of old way. Then I build new model to rennewedly estimate price of land's security. New model build from the demand of farm in security, adopt dynamic way to estimate.For confirm new model's validity, I use a practical case to test my new model. And through new model and old ways estimating result's comparative analysis to validate new model rationality and security of farmers lost land.
