摘　　要：SOTER是正在被广泛应用并具有强大空间分析能力的高新技术,与耕地地力评价模型结合,可充分发挥其地图化表现和空间分析能力。本研究以SOTER数据库为基础,建立了基于AHP法的耕地地力评价系统。并对长江上游典型区的彭州样区53个SOTER单元进行了评价,生成了相应的专题评价图。As a widely used hi-tech with a powerful function of geo-analysi s, SOTER demonstrated its potential in map visualization and spatial analysis afte r combined with natural productivity evaluation models. A natural productivity evaluation system was established based on SOTER and AHP. Fifty three SOTER uni tes were evaluated in the typical region-the pengzhou sample area of upper reach es of the Yangtse River, the evaluation results were mapped and the spatial dis tribution was analyzed.

关 键 词：SOTER数据库 耕地地力评估 层次分析法
