中文摘要	从系统学的观点出发,辩证地研究了干旱区地下水系统作为一个开放性的自然-人工二元复合系统所具有的功能及其环境,揭示了其脆弱性机理,建立了地下水脆弱性的评价指标体系,并根据模糊数学的原理,对石羊河流域各分区的地下水脆弱性采用二级模糊综合评判模型进行了评价.评价结果表明：民勤县和古浪县为极端脆弱,凉州区为严重脆弱,金昌市为一般脆弱.评价结果与实际情况相符合,说明该评价指标体系和评价方法具有一定的科学性和合理性.
英文摘要	From the viewpoint of the environment and function of a natural-artificial open system of ground- water, this article researched the characteristics of the groundwater vulnerability of Shiyang River Basin, defined the conception of groundwater vulnerability of the arid areas, revealed the inner reasons for the first time, and on the basis of which, the appraisal index system of groundwater vulnerability was established. The two-grade fuzzy comprehensive evaluation method was put forward based on the theory of fuzzy mathematics. The results of groundwater vulnerability of Shiyang River Basin showed that the groundwater was extremely fragile in Minqin city and Gulang city, quite fragile in Liangzhou district, and the groundwater is relatively fragile in Jinchang city. The results coincided with the fact, which indicated that the index system was quite scientific.
