A Study on the Mathematical Model for Evaluation of Environmental Quality

Yan Guixun  
This paper analyses some mathematical models and mixing weighted models specially. Based on the summary of their efficacy,we bring up the equalization,standardization and price expression for the number of various pollution elements,expression for the number of various pollution elements.We have given another mathematical model for evaluation of environmental quality and discussed its rationality,therefoe,solved the evaluation problem of the index which equals zero.This mathematical model gives a quick and reliable method for comprchensive evaluation of environmental quality or single item evaluation.For exam- ple,evaluation of air pollution,evaluation of water pollution etc.
