Research on the Air Quality Evaluation and Regional Interaction in Jing-Jin-Ji Region

摘要

The problem of air pollution has attached people's general attention nowadays. And the Jing-Jin-Ji region is badly polluted in particular. So this paper will mainly focus on how to evaluate the air quality and regional interaction in Jing-Jin-Ji region in a new scientific approach. Considering that the existing air quality evaluation methods have some weakness such as the single evaluation factor and the air pollution is regional, an air quality evaluation model based on the principle component analysis is developed in this paper firstly to set up a new comprehensive evaluation index which can evaluate the air quality more scientifically and more reasonably. Then, a regional interaction model is developed based on the gravity model and the analogy method to evaluate regional interaction in Jing-Jin-Ji region. The result and analysis are shown at the end of this paper. Finally, effective strategy can be put forward to solve the dreadful air pollution in this region and promote Jing-Jin-Ji coordinated development.
