The invention discloses an evaluation method of geological environment bearing capacity of a coastal zone. The evaluation method comprises the steps of establishing a coastal zone geological environment bearing capacity evaluation index system, obtaining index weights by using an unstructured triangular fuzzy number weight determination method and the evaluation indexes; and obtaining the geological environment bearing capacity according to the evaluation indexes and the index weights and outputting the geological environment bearing capacity. The unstructured triangular fuzzy number weight determination method in the evaluation method fully considers the importance of each index from the overall aspect during determination of the index weights, then an evaluation judgment matrix is established from three attitudes, i.e., pessimistic, neutral and optimistic attitudes in accordance with dyadic mood operators, the two methods are effectively merged, not only can the logics recognized by experts be satisfied, but also the judgment of decision makers to the importance of micro indexes under three different attitudes, i.e., pessimistic, neutral and optimistic attitudes is comprehensively considered, and the misjudgment of the original evaluation result based on a single attitude can be effectively avoided.
