摘要
以静升盆地为例,基于对地下水脆弱性概念的认识,以DRASTIC模型为基础,根据地下水脆弱性评价技术要求及静升盆地实际状况,构建了DRAIFAm指标体系,通过比较目前各种脆弱性评价方法,建立了PCSM-AHP评价体系,并利用该评价体系评价了静升盆地地下水脆弱性。结果表明,人工开采率和包气带介质是影响静升盆地地下水脆弱性的主要因子,地下水脆弱性从盆地东南向西北依次增大,与实际情况吻合较好,对静升盆地地下水的合理开发利用具有指导意义。
Taking Jingsheng Basin for an example, according to the national technical requirements of groundwater vulnerability assessment and the actual conditions of Jingsheng Basin, DRAIFAm index system is established in terms of DRASTIC model and understanding of groundwater vulnerability. Compared with the current methods of evaluating the vulnerability of groundwater, the PCSM-AHP evaluation system is established to evaluate groundwater vulnerability of Jingsheng Basin. The results show that artificial mining rate and vadose zone are the main impact factors~ the groundwa- ter vulnerability decreases from the northwest of the basin to the southeast of the basin; it accords with the actual situa- tion. Thus, it has an important guiding significance for further exploitation and utilization of groundwater.
