The construction of major railway projects traverses various geomorphological units characterized by complex topography and fragile ecological environments.Based on the geodetector model,this paper used Landsat remote sensing data and the CRITIC method,an objective and objective weight assignment method,to integrate four indexes of NDVI,WET,NDBSI,and LST to construct the remote sensing ecological index.The effect of ecological environment change along the railroad project and driving factors were analyzed by taking the railroad project which has been put into operation as an example.Through objective analysis of the spatial and temporal characteristics of the ecological environment along railway projects,this study aims to promote sustainable development of railways and regional environments.The results offer methodological support for evaluating the ecological environment of major railway projects and provide a foundation for developing policies for ecological restoration and protection along railway lines.
