摘　　要：针对传统DRASTIC方法在不同地域存在局限性,将聊城市作为研究区,各县市作为研究单元。考虑聊城市的地下水开采强度较大的现状,将地下水开采模数引入了评价指标体系,运用熵权原理计算出新指标体系的各指标权重。将评价结果与传统DRASTIC方法评价结果比较,能更好地反映研究区现状。Localization exists in different areas of traditional DRASTIC method,This paper makes Liaocheng City as a research area,each county as a research element.In view of high exploitation in Liaocheng at present,exploitation modulus is introduced into evaluation indicator system,next entropy weight is used to calculate the weights of every index.After comparing the results by two methods,the results of the improved method can reflect the research area＇s actual conditions better.
