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。

Abstract

As a widely used h-itech with a powerful function of geo-analysis

SOTER demonstrated its potential map visualization and spativeal alysis in combinativeon with soil degradativeon evaluativeon models. the soil deg radation evaluation system was established based on SOT ER and AH P. 53 SOT ER unites in the typical region of upper reaches of the Yang tse River were evaluated. the result evaluativeon was mapped and the spatial distribution was an-alyzed.
