摘要
针对传统DRASTIC方法中将指标离散化、权重定额划分及人类活动影响的问题,以通辽市地下水脆弱性评价为背景,应用模糊可变评价模型从水量及人类活动复合作用角度评价了地下水脆弱性。实例表明,该模型信息处理综合性强,评价结果可信度高,可应用于地下水脆弱性的综合评价中。
Traditional DRASTIC method has some drawbacks,such as dispersed index,fixed weights and neglected human activities.Taking the Tongliao City for an example,the variable fuzzy evaluation model is applied to assess the groundwater vulnerability from the aspects of water quantity and human activities.The results of instance show that the proposed model can handle the information very comprehensively and the evaluation results are more reliable.Thus,it can be used to comprehensive assessment of groundwater vulnerability.
