江西省鄱阳湖地区地下水中SiO2的分布特征及开发评价

论证了江西省鄱阳湖地区的地质环境背景和地下水中ＳｉＯ２的背景与分布特征及其与地下水的含水介质成分，地下水的ＣＯ２的含量，地下水的酸碱度，氧化还原环境，有机物质之间的关系，结果表明，地下水的ＳｉＯ２含量与含水介质中的ＳｉＯ２和有机质的含量，氧化还原环境有关，与地下水的ｐＨ值和ＣＯ２含量相关性非常显著，相关系数分别为－０．２８（Ｐ〈０．００１），０．２９（Ｐ〈０．００１），偏硅酸矿泉水资源丰富，有较好

THE DISTRIBUTION FEATURE AND DEVELOPMENT ASSESSMENT OF SiO2 IN GROUNDWATER IN THE AREA OF POYANG LAKE, JIANGXI PROVINCE

THE DISTRIBUTION FEATURE AND DEVELOPMENT ASSESSMENT OF SiO 2 IN GROUNDWATER IN THE AREA OF POYANG LAKE, JIANGXI PROVINCE demonstrated that the background of geologic envirenment, the background and distribution features of SiO 2 in groundwater in the area of poyang Lake, Jiangxi province and the relations between composition of the aguiferous medium in groundwater, SiO 2 content in groundwater, acidity and alkalinity in groundwater, axidation and reduction environment, organic material in groundwater. The result shows that SiO 2 content of groundwater and SiO 2 content of aguiferous medium, content of organic material, oxidation and reduction environment are interrelative, and pH value and CO 2 content of groundwater are correlated of very evidently, correlation coefficient are -0.28(p<0.001), 0.29(p<0.001). Metasilicic acid mineral spring water resourees in plenty, have a bette development and utilization value.
