| Abstract: | 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. |
