With the transformation and upgrading of industrial structure in China, the role of general aviation industry in national economy is more and more important. As an early stage of airport construction, the site selection become more critical when the number of general airports increased rapidly. In order to make the airport location more objective, a grey fuzzy evaluation model is built based on synthetic weighting method and grey fuzzy theory. Index weights which are measured by the AHP and entropy weight will be more reasonable. The grey fuzzy theory makes full use of evaluation information to promote the evaluation result more scientific. The model is applied to Mile airport site selection in Yunnan, the result shows that the Dongfeng farm No. 2 site is the best, it is consistent with the actual situation. Moreover, it is confirmed that the model is valid and practical.
