摘　　要：地下水脆弱性研究是保护地下水环境工作的基础。对地下水脆弱性进行评价,可为合理地保护、开发和利用地下水资源,实现地下水资源的可持续利用提供有益参考。应用熵权系数法、基于RAGA的投影寻踪模型以及多目标模糊模式识别模型等几种模型对三江平原地下水脆弱性进行评价,得出评价结果。将结果进行横向比较,分析几种评价方法各自的优缺点,为地下水脆弱性的评价提供新的思路和方法。The research of groundwater vulnerability is the basic work to protect the groundwater. For sustainable utilizing groundwater resource, evaluating groundwater vulnerability is necessary. Useful reference to protect ,exploit and utilize groundwater resource are provided rationally. Three methods are applied to evaluat the groundwater vulnerability in Sanjiang Plain. They are the entropy weight coefficient model, the projection pursuit classification model based on RAGA and the multipurpose fuzziness mode identify model. The satisfied results are acquired. After comparing the results each other, their advantages and disadvantages are analyzed, which offer new ways and methods for evaluating groundwater vulnerability.
