摘要
针对地下水易污性评价是识别含水层天然防污特性的基础,介绍了地下水易污性评价中常用的DRASTIC方法,指出该法忽略了指标连续变化的缺陷,基于模糊优选理论提出了三标度两步骤的AHP层次分析法,建立了含水层易污性的模糊评价方法,并以泉州市沿海地区为例,与传统方法及地下水综合环境质量评价结果进行了对比分析。结果表明,修正的AHP法评价结果更符合实际。
Assessment of groundwater vulnerability is necessary for knowing the characteristics of aquifer. The widely used DRASTIC model is introduced and analyzed, and this method has the shortcoming of neglecting the successive change of variables. Based on fuzzy optimization theory, the modified AHP method for vulnerability assessment of aquifer is proposed. The proposed method is applied in the coastal regions of Quanzhou city, and compared with the results calculated by DRASTIC model and the comprehensive assessment of groundwater quality. The result indicates that the AHP modified ratings and ranks are much closer to the facts.
