In the light of the practical situation of logistics distribution of agricultural products, we primarily select transportation factor, economic factor, environment factor, and other factors, to establish evaluation index system of site selection of distribution center of agricultural products. And then we adopt the analytic hierarchy process method to calculate weight of site selection of distribution center of agricultural products. Under the circumstance that the evaluation information is interval number, we use uncertain and multiple attribute decision making method to establish site selection model of distribution center of agricultural products. Finally, taking one city as an example, we discuss the application of this model in site selection of distribution center of agricultural products. The results of empirical analysis show that the model we established fully considers the randomness and uncertainty in the process of evaluation, so as to make the results of evaluation more objective, in line with reality. So the effect of evaluation is better as against the former real number evaluation calibration.
