A method for identifying an optimal corridor width includes: acquiring geographic information data of a target region; evaluating ecosystem service functions of the target region, and constructing an ecological source land in combination with a nature reserve; constructing a resistance surface indicator system, and obtaining a disaster susceptibility distribution result by using geological disaster distribution point data to correct a resistance surface, to thereby obtain a real resistance surface; importing data of the ecological source land and data of the real resistance surface into LINKAGE MAPPER to generate an ecological corridor; constructing an evaluation system of the optimal corridor width based on three aspects of cost-function-ecological benefits, and evaluating the ecological corridor by using an IEW-TOPSIS model to obtain the optimal corridor width of the ecological corridor. The method can compare and identify the corridor width most suitable for construction, and provide reference base for corridor construction.
