The development of industrial economy is the major force behind the rapid development of national economy. However, industrial pollution exerts huge pressure on the environmental carrying capacity with its largest share of environmental pollution. In this study, the characteristics of industrial discharge in Anhui of China were analysed to further understand its pollution discharge characteristics and major influencing factors. Its influencing factors were also analysed through Grey relative analysis, and the grey-relation degree between industrial pollution and each factor was quantitatively measured. Results reveal that in the period of 2005-2016, the total discharge of industrial wastewater in Anhui Province has shown a gradual, but unstable increase; the exhaust gas emission also has increased annually with a growth of 364%; and the common industrial solid waste has increased by 200%, whereas its rate of multipurpose utilization has been constantly improved. Grey relational coefficients indicate that the five industrial indicators are closely correlated according to the three indicators, including GDP per capita, industrial proportion and the number of environmental researchers. This finding indicates that rapid economic growth, unreasonable industrial structure and incompetence in environmental control are the major influencing factors. The conclusion is of great reference value to further understand the current situation of industrial pollution in China, optimize the industrial structure, reduce the discharge of pollutants, and explore the law between environmental protection and pollution effect.

Abstract


The development of industrial economy is the major force behind the rapid development of national economy. However, industrial pollution exerts huge pressure on the environmental carrying capacity with its largest share of environmental pollution. In this study, the characteristics of industrial discharge in Anhui of China were analysed to further understand its pollution discharge characteristics and major influencing factors. Its influencing factors were also analysed through Grey relative analysis, and the grey-relation degree between industrial pollution and each factor was quantitatively measured. Results reveal that in the period of 2005-2016, the total discharge of industrial wastewater in Anhui Province has shown a gradual, but unstable increase; the exhaust gas emission also has increased annually with a growth of 364%; and the common industrial solid waste has increased by 200%, whereas its rate of multipurpose utilization has been constantly improved. Grey relational coefficients indicate that the five industrial indicators are closely correlated according to the three indicators, including GDP per capita, industrial proportion and the number of environmental researchers. This finding indicates that rapid economic growth, unreasonable industrial structure and incompetence in environmental control are the major influencing factors. The conclusion is of great reference value to further understand the current situation of industrial pollution in China, optimize the industrial structure, reduce the discharge of pollutants, and explore the law between environmental protection and pollution effect.
