Environment sensitive area railway trend scheme green low-carbon evaluation method and device

The invention discloses a green and low-carbon evaluation method and device for a railway trend scheme in an environment sensitive area, and belongs to the technical field of railway engineering.The method comprises the steps that cases and evaluation indexes are compared and selected according to historical railway line schemes, and an engineering case big database is constructed; comparing the target railway with historical railway line schemes in the engineering case big database, and preliminarily extracting comparison and selection indexes; screening and classifying the comparison and selection indexes, and establishing a green low-carbon comparison and selection index system of the railway line trend scheme; according to the relative importance degree and the assignment standard, determining a weight coefficient of the comparison and selection index; and constructing a green low-carbon comprehensive evaluation model to obtain green low-carbon indexes of different railway line trend schemes of the target
