Research on the Methods of Cumulative Environment Impact Assessment in the High-Speed Railway Region

Article Preview

Abstract:

Combined with the characteristics of the high-speed railway regional environment system, the paper establishes a cumulative environment impact assessment model with the system dynamics in the high-speed railway regional, which is divided into three subsystems: economic, environment and pollution subsystems. Each subsystem is refined into a number of state indexes. The feedback relationships is set up between each state index and various subsystems, based on the Matrix method, Delphi, Analytic Hierarchy Process and environmental carrying capacity to establish comprehensive evaluation model of the cumulative environment impact assessment in the high-speed railway region. Finally the Chang-Yi high-speed railway is taken as an example.This paper is of the important theory and practice significance to promote the cumulative impact assessment level and social environment benefit of the high-speed railway regions.
