Abstract:Taking Shanghuang experimental area of Ningxia as a case study,changes of cultivated land and farm household economic behavior were analyzed using historical data,PRA investigation methods and GIS.Results show that cultivated land changes affect farm household economic behavior both within and outside the agricultural system.Planting structures and utilization forms of crop land are the most obvious changes within the agricultural system,whereas increased income and export labors of farm household economic behavior constitute the outside changes.
Keywords:Loess hilly-gully region  Cultivated land change  Farm household economic behavior  Agricultural system
