The application of improved FUZZY-AHP method in groundwater quality evaluation
Groundwater pollution seriously threaten the environment if controlling steps are not implemented immediately,groundwater quality evaluation is one of the significant means to solve these problems.As impacting factors that are evaluated their influences on groundwater pollution,weights of indicators and attributes are determined by the Analytic Hierarchy Process (AHP) method which is performed by matrix calculations.Considering defects of the method for sorting,Improvement on the sorting method will be made.Then,combines the weights that respectively determined by the AHP method and by the improved AHP method with the fuzzy membership degree,to evaluate the level of groundwater quality.The method not only overcomes deviations of personal opinion for experts,but also avoids errors brought by fuzzy uncertainty; Contrast with these two kinds of evaluation methods,the improved AHP method can be more successful to sort the factors,example of application testified the reliability of above method.
