Fuzzy概率模型在淮北平原地下水水质评价中的应用

Application of Fuzzy Probability Model in Groundwater Quality Evaluation in Huaibei Plain

地下水质量正确评价是区域水环境保护的重要前提。依据地下水环境质量分类标准,运用Fuzzy模型对研究区内的地下水质量进行评价。在对区域环境内的各单项污染指标进行分级评价的基础上,考虑到各单项污染指标在总评价中的地位,将各单项污染指标的作用综合起来,建立了Fuzzy概率模型。实例研究结果表明:Fuzzy概率模型可行,原理简明,淮北地区地下水环境的综合质量属于Ⅲ级,从而在整体上可以看出淮北地区地下水的总的污染程度属于中等,符合当地的实际情况。为合理的评价地下水水质和制定污染保护的措施奠定了基础。

Correct evaluation of groundwater quality is vital for regional water environmental protection. According to the quality standard for groundwater, fuzzy probability model was applied I this paper to evaluate groundwater quality in the study area. Based on the grading to all pollutant indices in the regional environment, taking into account the status of all pollutant indices in the overall evaluation, we synthesized the role of all pollutant indices, and established a fuzzy probability model. A case study results show that the fuzzy probability model is feasible, the principle is concise, the comprehensive quality of groundwater environment is grade Ⅱ , groundwater pollution in the whole region is moderate, which is consistent with the actual situation.. This study laid foundation for correct evaluation of groundwater quality and constituting pollution control measures.
