The Environmental Impact Assessment of Power Transmission Project Based on Fuzzy Theory

Abstract

As environment impact has become the important constraining factors to the power transmission project, so it is necessary to expand the scope of environmental impact assessment (EIA) to provide some information to relevant departments for decision-making. This paper selected fuzzy comprehensive evaluation method to assess the environmental impact, which is fit for the uncertainties of the EIA. The results show that the project's impact on the environment is satisfactory and it still exists insufficient in environment protection and the improvement is still potential. The innovation of this paper is to assign the comprehensive evaluation vector by considering the weighted average confidence degree of the comments set-valued, so it can calculate the assessment values more accurately.
