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。
Abstract
We analyzed the limiting factor for ecological suitability of hulless barley in Tibet,and elaborated the establishment and weight of fac-tor system of ecological suitability evaluation of hulless barley in Tibet based on GIS. Results showed that①Analytical Hierarchy Process( AHP) method was good to confirm the weights of all indexes;②the established index system could better evaluate the ecological suitability of hulless barley in Tibet.
