【摘要】 针对当前地下水脆弱性评价体系的不完善,以DRASTIC模型为基础,从人为因素和自然因素两方面着手,构建了DRAITG指标体系,通过比较目前各种脆弱性评价方法,建立了EW-AHP-SIM脆弱性评价体系,并利用DRAITG和EW-AHP-SIM评价了太原市小店区地下水脆弱性.结果表明,从时间上看,由于地下水开采强度的减弱,小店区地下水脆弱性从2003年至2010年呈下降趋势;从空间上看,研究区东北部的低山丘陵区地下水脆弱性相对较低,研究区西部和南部的汾河及潇河阶地区地下水脆弱性相对较高,中部的冲积平原区,由于地下水水位、包气带岩性、含水介质、地形坡度的复杂变化,地下水脆弱性分区相对复杂.研究结果可为小店区地下水的进一步开发利用提供指导.更多还原

【Abstract】 Considering the shortcomings of the current groundwater vulnerability evaluation system,according to the human factors and natural factors of the Xiaodian District,DRAITG index system is estabilished in terms of DRASTIC model.Compared with the current methods of evaluating the vulnerability of groundwater,the EW-AHP-SIM evaluation system is established to evaluate groundwater vulnerability of Xiaodian District.The results show that the groundwater vulnerability spatially decreased from the northeast part of the Xiaodian District to the southwest and temporally tended to lower.Research results would provide an important theoretical guidance for further exploitation and utilization of groundwater.更多还原
