| Abstract: | 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. |
