Abstract: The characteristics of engineering geology environment of Qingdao City are systematically analyzed by using the Analytic Hierarchy Process. The weight of the fifteen index factor affecting the engineering geo-environmental quality can be ascertained through determining the nature and calculation, and the results are more reasonable and scientific. The Fuzzy mathematics, a powerful tool dealing with the fuzzy problems, has been comprehensively used to evaluate the engineering geo-environmental quality of the main functional zone of Qingdao City, and the evaluation map of the urban engineering geo-environmental quality of the main functional zone of Qingdao City can be the basis of engineering construction plan and economic development's arrangement.
