Aiming at the character that the evaluation factor s possess the multi2hierarchy and fuzzy characters, this paper esta lishes an AHP2 ased fuzzy comprehensive evalua2 tion model and distinguishes the groundwater environmental vulnera ility zones of the N ingling Country and analyzes the characters of every gr oundwater environmental vulnera ility r egion. Key words: groundwater environmental vulnera ility; the partitioning standard; partitioning of vulnera2 ilities; AHP; fuzzy comprehensive evaluation 地下水环境脆弱性是指地下水环境由于自然
