Evaluation and Analysis of Groundwater Quality Based on Fuzzy Mathematics Theory
Water environment is a complex dynamic system,and water environment quality has the characteristics of certainty and uncertainty,precision and ambiguity,and quantity at the same time.The solution of such problems can be solved not only by the deterministic model,but also by the stochastic model and the fuzzy model.Taking the measured data of groundwater observation well in Shiyang River Basin in September 2020 as an example,this paper uses fuzzy mathematics theory and refers to groundwater environmental quality standard(GB/T14848-2017),selects main evaluation factors,establishes fuzzy relationship matrix,and conducts a comprehensive evaluation of groundwater in Shiyang River basin.The results show that the fuzzy comprehensive evaluation model can objectively reflect the current situation of water quality,and the evaluation results are consistent with the reality,which is an effective and reliable evaluation method.
