摘    要:在大沽河地区自然地理和水文地质调查的基础上,利用MapInfo建立缓冲区功能来划分评价区域,运用日前常用的DRASTIC方法进行了全面的脆弱性评价.研究结果表明:大沽河地下水库大部分地区约60.8%属于脆弱性中等的区域,25%属于脆弱性较强的区域,另外还有10.1%属于脆弱性较弱的区域,即大沽河地下水库库区是相对脆弱的,应尽量避免兴建污染性强的项日,减少化肥和农药的使用,防止地下水污染的发生和发展.

关 键 词:大沽河  地下水库  脆弱性评价  DRASTIC模型

Abstract:Based on the investigation of geographic and hydrogeologic conditions in the Dagu River valley, a comprehensive vulnerability assessment was carried out with the popular DRASTIC model, powerful map inquiry and calculation capacity of MapInfo. The result indicates that 60. 8% of its valley belongs to moderate vulnerable area, 25. 0%-highly vulnerable area, and 10. 1%-weekly vulnerable area. Therefore, all of the Dagu River groundwater reservoir is comparatively vulnerable to groundwater contamination. High pollution projects should be avoided, and fertilizers and pesticides should be used reasonably to prevent the groundwater contamination.
Keywords:Dagu River  groundwater reservoir  vulnerability assessment  DRASTIC model
