Research on groundwater quality evaluation with fuzzy mathematics

摘要

Given the ambiguity of the type and classification in groundwater quality standards, this paper based on fuzzy mathematics theory, take TDS, fluoride and other components as the nine evaluation factors, determine its weight according to the pollution of different factors on water quality; using fuzzy membership to describe the classification boundaries of the evaluation in water quality. Established a number of pollution assessment factors of fuzzy sets such as evaluation set, membership function and weight set;after the compound operation of fuzzy matrixes, using the maximum membership degree law, to evaluate the groundwater quality of a monitoring well in study area,the conclusions are objective.
