In order to solve the urban environmental burden brought by the construction of urban rail transit,the environmental impact factors of urban rail transit are analyzed and determined.Taking Nanning Metro Line 6 as an example,this paper selects specific indicators by public participation method and establishes a hierarchical model of environmental impact assessment index system for urban rail transit planning.The weight of the index system is determined by the analytic hierarchy process,and finally the comprehensive demonstration results of the environmental impact of urban rail transit planning are obtained,which provides a theoretical basis for urban rail transit planning and construction.
