新疆石河子地区地下水氟分布及富集因素分析

摘要

The too high or too low fluoride content of groundwater will be harmful to human health. A study of groundwater fluorine in plain of Shihezi area in Xinjiang was taken by analyzing 23 groundwater samples by using SPSS and MAPGIS software. Results show that the fluorine concentration is gradually increased from the south to the north horizontally. Vertically, the fluorine concentration in deep confined water is higher than that in shallow confined water. Fluorine groundwater primarily comes from the coal⁃bearing strata in southern mountainous area and the discharge of three wastes by chemical enterprises. In addition, the climate, runoff, geological and groundwater chemical environment are the major factors of groundwater fluorine enrichment.%地下水氟含量过高或过低均会危害人体健康，以新疆石河子地区平原区地下水中的氟为研究对象，运用SPSS及MapGIS等软件对23个地下水水样测试结果进行分析。结果表明：水平分布上研究区内地下水中氟的含量从南向北呈逐渐升高趋势，垂向分布上深层承压水氟含量高于浅层承压水的；地下水中氟的主要来源为南部山区煤系地层，以及区内化工企业排放的“三废”等；地下水中氟富集主要受气候、径流等地质条件和地下水化学环境条件等影响。
