In this study, selenium content, soil nutrient elements and environmental quality are considered comprehensively as the main factor, weight of each index is calculated by analytic hierarchy process and Yaahp software, and spatial distribution of evaluation results is reflected by Geographical Information System. Wucheng district is taken as a case area and classified into some regions for selenium utilization. The southern mountainous and hilly area is suitable for the development of selenium-rich ecological tourism, the northern alluvial plain is suitable for the development of selenium-rich agriculture, Zone III-IV are not suitable for natural selenium-rich agriculture, Zone V is forbidden to farm because of the pollution of heavy metals.
