摘　　要：分析了西藏青稞生态适宜性限制因子,阐述了基于GIS进行青稞适宜性评价因子体系的建立,并确定权重。结果表明:层次分析法能较好地确定各因子的权重;建立的评价因子能较好地评价西藏青稞的生态适宜性。We analyzed the limiting factor for ecological suitability of hulless barley in Tibet,and elaborated the establishment and weight of factor system of ecological suitability evaluation of hulless barley in Tibet based on GIS. Results showed that 1 Analytical Hierarchy Process（ AHP）method was good to confirm the weights of all indexes; 2 the established index system could better evaluate the ecological suitability of hulless barley in Tibet.
