Embodiment Construction

[0021] This example specifically studies the dominant factors affecting the impact of economic growth on pollutant emissions in the Suzhou area. Suzhou City is located in the middle of the Yangtze River Delta, in the southeast of Jiangsu Province. Suzhou City has 5 cities and 7 districts under its jurisdiction, with a total area of ​​8488.42 square kilometers, of which the hilly area accounts for 2.65%, and the water area accounts for 42.52%. The urban area is 1650 square kilometers. By the end of 2007, the city's total population was 6.2443 million, and its gross domestic product (GDP) was 570.085 billion yuan. As of 2006, its GDP growth rate ranks first among the 15 cities in the Yangtze River Delta region, its total GDP ranks fifth among all cities in the country, and its total industrial output value ranks second. Suzhou is one of the most densely populated and ecologically fragile areas in China. Relatively limited resources and deteriorating ecological environment hav...

Abstract

The invention provides a method for determining dominant influence factors of pollutant emission. The method comprises the following steps of: firstly, determining the types of pollutants and acquiring historically measured data of pollutant emission amount; secondly, selecting factors which affect the pollutant emission amount and acquiring the historically measured data of the factors; and finally, calculating grey relation degrees by using a grey relation analysis method and performing sorting according to the size of the grey relation degrees so as to determine the dominant influence factors of the pollutant emission. In the invention, the major dependency relationship between the pollutant emission and an environmental economic system can be comprehensively evaluated by a simple principle and a few data, the optimization and updating of an industrial structure can be effectively implemented and the industrial pollution can be effectively controlled after the dominant factors which affect the emission of various pollutants are determined, and thus, the task of energy conservation and emission reduction is completed and the sustainable region development is realized.

Description

technical field [0001] The invention relates to a method for determining the dominant factors affecting pollutant discharge, more specifically, a method for determining the dominant factors of pollutant discharge based on gray correlation degree. Background technique [0002] The relationship between economic growth and environmental quality is highly uncertain. Neither a natural ally nor a natural enemy. Rapid economic growth has a negative impact on the environment as it is often accompanied by industrial expansion, urbanization and the continuous exploitation of renewable or non-renewable resources. But at the same time, growth also creates conditions for improving the environment. The most famous theory for studying the relationship between economic growth, environmental quality and pollution emissions is the Environmental Kuznets Curve (EKC) proposed by Grossman et al., Selden et al. based on empirical data. The relationship between pollution extends to the relations...
