Abstract To scientifically evaluate the suitability of the selection of small underground drinking water sources, twenty-six indicators were selected from the point of view of the water quality safety, water quantity safety, and economic security. Based on the analytic hierarchy process (AHP), a mathematical model of evaluation indicator system was established. The weight of factors was defined by the method of document data and expert questionnaire, and these weights were synthesized under single criterion. These factors were classified and quantified according to the laws, technical standards and statistical data. By the calculation of factor scores and weights, the evaluation results can be got. The evaluation system and model were suitable for quantitative analysis and scientific decision-making on site selection of decentralized underground drinking water sources in northern rural areas.
