通过对1720个水质分析样品资料的深入分析与计算,系统地评价了洞庭湖区浅层地下水质量,指出了浅层地下水安全供水方向,并提出了安全供水措施及建议.计算结果认为,洞庭湖区浅层地下水中的污染因子主要为Fe、Mn、PH、NH_4-N及NO_2-N,其次为NO_3-N、Be、COD,共8个因子,基本上没有遭受重金属污染:湖区浅层地下水水质整体较好,以优质水为主,占39.37%,合格水占26.04%;不合格水(较差水)占34.59%.

Based on analyzing the test data of 1720 groups of water samples collected from the Dongting Lake area, the authors conducted a quality assessment of shallow groundwater in this area. On such a basis, this paper presents the secure water supply directions and puts forward suggestions and measures for secure water supply. The test data indicate that the shallow groundwater is mainly contaminated by the following eight indexes : Fe, Mn, pH, NH_4-N, NO_2-N,NO_3-N, Be and COD. On the whole, the shallow groundwater in this area shows good quality, and hence it is mainly assigned to high quality water (39.37%), and subordinately to qualified water (26.04%) and unqualified water (34.59%).
