Research on Evaluation of Wuhan Air Pollution Emission Level Based on Entropy weight Method

Abstract

Abstract Along with the increasing development of society and economy, it is becoming more and more important to keep the balance for environment and development. In this context, air pollution control has become a key factor affecting economic and social development. Taking Wuhan’s air pollution situation as a sample and using the entropy method, this paper constructs an evaluation model of air pollution emission level, and evaluates the air pollution emission level of Wuhan. We can find that the total emissions of air pollution for Wuhan shows a gradual upward trend over time, which not only brings about economic growth, but also brings about the increasing emission of air pollution. And the air pollution in Wuhan mainly comes from industrial pollution. Meanwhile, among the weights of air pollution emission indicators, sulfur dioxide emission indicators and industrial sulfur dioxide emission indicators account for a large weight. It can be seen that although the overall pollutant emission level of Wuhan shows a downward trend, while paying attention to economic growth, we need to pay more attention to emission reduction and fossil energy consumption. Therefore, the government can reduce air pollution by focusing on detecting major polluting industries, promoting industrial technological progress and innovation, and strengthening the effective implementation of emission trading system.
