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。
Based on the understanding of the concept of groundwater vulnerability and based on the DRASTIC model, based on the understanding of the concept of groundwater vulnerability, a DRAIFAm indicator system is constructed according to the technical requirements for groundwater vulnerability assessment and the actual conditions of the static basins. By comparing the current vulnerability assessment Method, the evaluation system of PCSM-AHP was established and the vulnerability of groundwater in Jingsheng basin was evaluated by using this evaluation system. The results show that artificial exploitation rate and medium with aeration zone are the main factors affecting groundwater vulnerability in Jingsheng basin. The vulnerability of groundwater increases from southeast to northwest of the basin, which is in good agreement with the actual situation. The reasonable exploitation of groundwater in Jingsheng basin Use is instructive.
