摘　　要：以长江上游典型区———彭州市为例,在该区SOTER(1∶50000)数据库的支持下,建立了基于AHP法的土壤退化评价系统。对样区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-analysis, SOTER demonstrated its potential map visualization and spatial analysis in combination with soil degradation evaluation models. The soil degradation evaluation system was established based on SOTER and AHP. 53 SOTER unites in the typical region of upper reaches of the Yangtse River were evaluated. The result evaluation was mapped and the spatial distribution was analyzed.
