Environmental impact evaluation for thermal power project based on combinational weight and TOPSIS method

In electricity production and supply system of China, thermal power continues to dominate a larger proportion. In recent years, be influenced by energy-saving emission reduction and low carbon development policy, the environmental impact issue of thermal power project aroused great attention. This study has established a comprehensive evaluation system by analyzing integrated comprehensive effects of the environment caused by thermal power project. Combining with AHP theory, entropy theory and TOPSIS evaluation ideas, the study created a set of scientific assessment model. The research has verified that the validity of the model through empirical studies. And it provided a good theoretical basis for environmental management comprehensive thermal power project.
