Analysis on Factors Affecting the Air Quality in Beijing City Based on Grey Relation Theory

Abstract:

with the sustainable development of our economy and the increase of people's living standards, China's air quality has deteriorated sharply. It is important to study the factors affecting the air quality. The study can help to reduce the pollution of the environment and promote the coordinated development of economy and environment. Using the grey correlation theory,this paper analyzed the factors influencing air quality in Beijing city. Results show that, in accordance with the influence factors for air quality from big to small order, influence factors are as follows: energy consumption quantity, the number of resident population, GDP, investment in science and technology, investment in environment protection. Therefore , we need to focus on energy consumption reduction and population control to increase the air quality in Beijing City.
