摘　　要：以四川省马尔康县为研究区域,运用地理信息系统(GIS)技术,将遥感技术和GIS技术相结合。阐述了土地适宜性评价的概念和内涵,依据土地适宜性的评价原则和主要影响因素选取评价因子。运用层次分析法(AHP)计算评价因子的权重值,并采用DTM模型分析确定耕地、林地和草地的坡度值,依此建立土地适宜性评价模型,进行叠加分析,得出耕地、林地和草地适宜性等级图,进而为确定最佳的土地利用方案提供科学依据。The combination of the remote sensing and GIS technologies was applied to study the land in Maerkang County.The notion and meaning of land suitability assessment.and land suitability evaluation based on the principles and the main factors evaluation factor selection were explained.Based on analytic hierarchy process（AHP）calculating and evaluating the value of the weight factor,and DTM model analysis calculating farmland,woodland and grassland slopes,a land suitability evaluation modelr overlay analysis was established to make farmland,woodland and grassland suitability class map,and to determine the best land-use programs for providing a scientific basis.
