- 摘要：以苍溪雪梨为例，利用遥感(RS)和地理信息系统(GIS)技术，采用层次分析法(AHP)和空间分析法，结合苍溪雪梨生长发育适宜的气候、地形等生态环境因子，研究了苍溪雪梨在四川省的适宜性分布范围，对其适宜性分布进行评价，以期为苍溪雪梨在四川省的适宜性种植结构调整提供参考。结果表明：通过遥感与GIS技术分析所得适宜性结果与苍溪雪梨资源实际分布范围基本吻合。四川省扩引种苍溪雪梨的总适宜面积为1198万km2，占四川省总面积的2487%。其中最适宜性面积069万km2，占四川省总面积的143%；较适宜性面积284万km2，占四川省总面积的589%；适宜区约有846万km2，占四川省总面积的1756%。关键词：苍溪雪梨；GIS；加权叠加；环境因子；生长适宜区
