Atmospheric environment impact assessment of thermal power plant
Due to the excess consumption of natural resources and the severe deterioration of the environment, people are having a growing consciousness of environmental protection and more concerned of air pollution problems. However, the thermal power plant, as one of the main pollution sources, burns a large amount of fossil fuels and discharge pollutants which cause serious atmospheric pollution. Therefore, it is of great importance to evaluate the environmental impact accurately in order to support administrators on decision making. In this paper, a new assessment model through combining the support vector machine and the BP networks based on particle swarm optimisation is presented. This model makes more accurate evaluation by taking the advantage of both SVM and BP networks and avoiding their defects. An actual instance addressed in the paper shows that this method is effective and practicable.
