Aiming at exploring the ecological effect of high-speed railway construction and operation, this paper establishes a green ecological assessment index system based on the concept of sustainable development, and sets up a green ecological assessment model based on unascertained measure and AHP. During the assessment process, the author firstly constructs the unascertained judgment matrix by introducing the unascertained theory, secondly determines index classification weight by AHP, and thirdly identifies the green grade according to the confidence criterion. On this basis, the author defines the green assessment grades. Then, the author carries out green ecological assessment of Beijing-Shanghai HighSpeed Railway (Xuzhou-Shanghai Section). The ecological score is 7.0089 and the resulting color is turquoise, which is consistent with the concept of sustainable development. The result shows that it is feasible to combine the unascertained measure and AHP into an ecological assessment method for high-speed railway construction project.
