Environmental impact assessment of road engineering based on analytic hierarchy process
CHEN Chao-feng
Abstract：In order to accurately evaluate the impact of road construction on the environment,the application of multi-level combined index system method in environmental impact assessment was studied.Taking the construction of Huandao North Road in Xiaozuo Town as an example,combined with the multi-level index system method,the environmental impact assessment of road engineering is carried out,and the analytic hierarchy process is used to qualitatively construct three levels,three environmental subsystems and nine environmental factors.The total environmental impact and environmental subsystem impact are calculated by index system method,and the influence degree of parameters in the environmental system is directly judged by combining classification rules.The results show that the project has a slight impact on the overall environment,a moderate impact on the natural environment(mainly on noise and surface water),a slight impact on the ecological environment,and no impact on the social environment.In the process of assessment,not only the total environmental impact degree can be judged by classification,but also the impact of environmental subsystems and environmental factors on the environment can be evaluated intuitively.The results indicate that the application of AHP and index system method in environmental impact assessment is convenient and clear.
