The Application of Grey Correlation Analysis in the Atmospheric Environment Quality Assessment

The gray clustering method is a new clustering method, which is establishment and development on the fuzzy mathematics, it has been widely used in social and economic systems in various fields, and displayed its unique advantages in actual. Gray clustering method is used to conduct environmental quality assessment, which is based on the using the environmental monitoring data, and limited to the spatial and temporal scales, as described in the environmental system is seen as a gray system, and the quality of the environment is affected by a number of factors, some factors are difficult to measure and understand, and some factors have not yet been recognized. Thus, the environmental system can be studied as a gray system. In this paper, the application of gray correlation model of the atmosphere surrounding a power plant to evaluate the quality of the environment.
