Taking household\'s land use preference as classification rule, household agent types were divided though classification tree. Different choosing process of current production strategies and theirs probabilities after expiration of GFGP chosen by various types of household agents\' were put forward by experience-weighted attraction model based on bounded -rational approach. Finally, forecasting the results of households\' recultivation behaviour after the expiration of GFGP by scenario analysis method. The results show that relative policies are useful to rectify deviation of households\' bounded-rational behaviours and reinforce outcomes of GFGP.
