Abstract：In order to supply land utilization policy in Loess Plateau with decision basis, the Xiji County of Ningxia is taken as a case,where the policy of returning land for farming to forestry was carried on earlier than most of other areas in Loess Plateau,and TM images of 1990 and 2005 were chosen to analyze the variation of all land utilization types of Xiji County between 1990 and 2005 from the perspective of land utilization structure and spatial landscape pattern,then the variation of land utilization in the course of returning land for farming to forestry was mastered.
