- 摘要:
- 对于目前广泛应用于地下水脆弱性评价中的DRASTIC模型进行了评述，并指出了该模型存在的问题。根据三江平原的实际情况，提出了基于熵权的DRASCLP评价方法，该方法选取地下水埋深等7个评价指标作为评价因子，应用熵权系数法确定各因子的权重，并结合GIS的空间叠加功能对该区的地下水脆弱性进行评价。评价结果表明：三江平原地下水脆弱性从西北方向向东南方向呈现逐渐减弱趋势，该评价结果为三江平原地下水资源的开发利用和保护提供决策依据。
- Abstract:
- The DRASTIC,one of the wildly applied systems for groundwater vulnerability evaluation,is reviewed and the main problems are analyzed.According to the practical situations of Sanjiang Plain,an evaluation method namely DRASCLP is suggested based on the Entropy Weight.In this method,seven indexes are selected as the parameters,and the weight of each factor is calculated by the entropy-weight coefficient method,and the space superposition function of GIS technology can be used to evaluate groundwater vulnerability.The results show that groundwater vulnerability presents the trend of decrease from northwest to southeast,which provide a decision basis for utilization and protection of groundwater resource.
