摘要 针对DRASTIC模型在地下水脆弱性评价应用中存在的不足,将模糊分析评价理论及三标度分两步的层次分析法引入地下水脆弱性评价中,构建了一套改进的DRASTIC模型,并将其运用到祁县东观镇地下水脆弱性评价的实例研究中,计算结果表明东观镇地下水脆弱性大致呈正态分布,偏低脆弱性地区占评价区域的38.3%,偏高脆弱性地区占61.7%,整体上,地下水系统易受污染、脆弱性偏高,与实际情况基本吻合.与传统DRASTIC模型相比,改进模型算得的地下水脆弱性等级变化更灵敏、分布范围更精确,更值得推广应用. According to the defect of DRASTIC model in groundwater vulnerability assessment, a modified groundwater vulnerability assessment model was formulated, based on fuzzy analysis theory and an improved analytic hierarchy process method with three index and two steps. It was applied to the evaluation of the groundwater vulnerability in Dongguan Town, Shanxi Province. The results show that groundwater vulnerability is approximately in normal distribution in the whole, and low vulnerability areas account for 38.3%, while high vulnerability areas account for 61.7%, the whole groundwater system is subject to pollution, which is consistent with the actual situation. Compared to DRASTIC model, the results derived from modified model is more sensitive and the distribution is more precise. So it deserves to be used widely.
