摘　　要：以太湖流域典型平原地区苏州市为例,结合研究区水文地质特点,选取浅层地下水水位埋深等6项参数作为评价因子,建立基于墒权的浅层地下水脆弱性评价DRITuTmE模型。将评价模型与GIS技术相耦合,形成研究区浅层地下水脆弱性分区图,并进行研究区浅层地下水脆弱性评价。评价研究结果表明:所建立的评价模型避免了人为因素的干扰,能够真实地反映苏州市浅层地下水脆弱性程度。Here presents the study on shallow groundwater vulnerability（ SGWV） assessment for Suzhou city,a typical plain area in the Taihu Basin in China. According to the specific geological conditions of the area,groundwater depth and other five parameters are selected as assessment factors,and the DRITu Tm E model based on entropy weight is established to assess the SGWV in Suzhou plain area. Based on the assessment model and GIS technique,the SGWV assessment is conducted and the vulnerability distribution map is drawn. The assessment result shows that the improved model can eliminate subjective errors and can reflect the shallow groundwater vulnerability characteristics of the study area,and the result is useful for the shallow groundwater utilization and protection.
