Abstract In this study, the geological, ecological and social environment of the northwest margin of Horqin sandy land are analyzed by analytic hierarchy process (AHP). An evaluation index system is established to adapt to the development of agriculture and animal husbandry as target layer, and the comprehensive indexes of regional eco-geological environment quality are calculated to evaluate the eco-geological environment. According to the results, it is considered that the eco-environment impacts on the whole evaluation results more than the geological and social environment does, with land quality as the key factor. Of all the evaluation units in the study area, 86% are at a medium or lower level. The results are of great significance to correctly understand the eco-geological environment of the area.

Key words： analytic hierarchy process eco-geology environment evaluation GIS Horqin sandy land Inner Mongolia
