摘　　要：Environmental impact evaluation system boundary of high-speed railway was defined based on the total life cycle theory,and the index system to evaluate the environmental impact of high-speed railway was established with the fuzzy analytic hierarchy method,and the matter-element evaluation model was established on the basis of the extension theory.By calculating its comprehensive interrelatedness,the evaluation rank of environment impacts of high-speed railway was determined.The numerical example shows that the model has vast prospect,which can not only expand the application areas of extension theory,but also change the traditional evaluation methods and provide new ideas and means for environmental impact evaluation of high-speed railway.Environmental impact evaluation system boundary of high-speed railway was defined based on the total life cycle theory, and the index system to evaluate the environmental impact of high-speed railway was established with the fuzzy analytic hierarchy method, and the matter-element evaluation model was established on the basis of the extension theory.
