基于模糊综合评价法的丹东市地下水质量评价

Quality Appraisal of Groundwater in Dandong City based on Fuzzy Comprehensive Evaluation Method

文章以丹东市为例,提取了试验区深层第二含水组与浅层地下水作为评价水样,然后利用模糊综合评价模型和水质分析数据,客观科学的评价了该区域地下水质量。结果表明:水质原生组分和铁、锰、氟等微量组分超标为引起丹东市地下水水质变差的主要因素;丹东市地下水质整体处于Ⅰ-Ⅲ类,评价结果基本能够反映该区域实际状况,所构建的模糊综合评价模型具有一定的科学性与合理性。

Taking Dandong City as the example, deep second aquifers and shallow groundwater in test area was dropped as the evaluation water sample, then using fuzzy comprehensive evaluation model and water quality analysis data, the quality of groundwater in this area was evaluated objectively and scientifically. The results show that: original component of water quality and micro-components of iron, manganese and fluorine are out of limits, that is the main reasons resulting in poor groundwater quality in Dandong City;the quality of groundwater in Dandong City belongs to category of Ⅰ-Ⅲ on the whole, the evaluation results can reflect basically the actual situation of this area, and the fuzzy comprehensive model established is scientific and reasonable.
