| 中文摘要: |
| 本文对当前地下水脆弱性评价的方法进行了评述。指出了目前应用最为广泛的DRASTIC法的局限之处，在充分考察中国平原盆地水文地质条件的前提下，提出了基于层次分析的DRUA评价方法。该方法是选取影响地下水脆弱性的地下水埋深等4个评价参数作为评价因子，应用层次分析法确定各因子的权重，结合GIS空间分析功能对地下水本质脆弱性进行评价。 |
| 英文摘要: |
| The current used methods for evaluating the vulnerability of groundwater are presened.The shortcoming of the widely used DRASTIC method is pointed out. Based on the investigation of the hydrogeology conditions in plain area of China, a method namely DRUA based on the principle of hierarchy analysis is suggested. In this method the water table, net recharged water amount, kind of unsaturated media layer and kind of aquifer are selected as the parameters affecting the vulnerability of groundwater, and the GIS technology is introduced to help implementation of evaluation. The application to evaluation the groundwater situation in Shijiazhuang district shows that this method can reasonably reflect the effect of various parameters in evaluation. |
