中文摘要:
      在综合阐述甘肃省自然地理及区域水文地质条件的基础上,利用2014—2015年完成的614组地下水及地表水水质测试分析数据(包括感官指标、一般化学指标、矿泉水界限指标、矿泉水限量指标和污染指标),依据《食品安全国家标准 饮用天然矿泉水》(GB8537-2018),系统分析归纳总结了甘肃省饮用天然矿泉水类型、分布及产出特征。结果表明,省内饮用天然矿泉水基本类型主要有锶型、偏硅酸型、锂型、碘型、锌型和硒型矿泉水六类,具备1项或1项以上的界限含量指标达到标准的水点共有417处,其中锶型(含复合型)矿泉水411处,是甘肃省的主要矿泉水类型,其余类型的矿泉水仅零星出现;按产出的地貌单元分析,锶型矿泉水产出率由多到少依次分布于河西走廊(82. 2%)、陇东黄土高原(80. 2%)、甘南高原(67. 2%)、北山区(61. 5%)、祁连山—阿尔金山区(59. 7%)、陇西黄土高原(53. 5%)、陇南山地(19. 6%);按不同类型地下水及地表水中锶含量达标率分析,白垩系、新近系碎屑岩类孔隙裂隙水最高(平均85. 4%),其次为第四系松散岩类孔隙水、断裂破碎带裂隙孔隙水、基岩裂隙水和碳酸盐岩裂隙岩溶水(平均53. 2%),地表水最低(平均32. 7%)。新近系—白垩系碎屑岩类孔隙裂隙水中锶元素最易富集。研究结果对甘肃省矿泉水资源的勘查开发利用有重要的指导作用。
英文摘要:
      Based on the comprehensive description of the physical geography and regional hydrogeological conditions of Gansu Province, 614 groups of groundwater and surface water quality test and analysis data (including sensory index, general chemical index, mineral water boundary index, mineral water limit index and pollution index) completed in 2014 ~ 2015 are used according to “the national food safety standard Drinking natural mineral water”(GB8537-2018), systematically analyzed and summarized the type, distribution and output characteristics of drinking natural mineral water in Gansu province. The results show that there are 6 basic types of drinking natural mineral water in Gansu Province: strontium type, metasilicic acid type, lithium type, iodine type, zinc type and selenium type. There are 417 water points with one or more limit content indexes reaching the standard, among which 411 strontium type (including composite type) mineral water is the main type of mineral water in Gansu Province, and the rest types are only sporadic. According to the geomorphic unit analysis, the strontium type mineral water production rate is distributed in Hexi Corridor (82. 2%), Longdong Loess Plateau (80. 2%), Gannan plateau (67. 2%), Beishan district (61. 5%), Qilian Altun mountain area (59. 7%), Longxi Loess Plateau (53. 5%) and Longnan mountain area (19. 6%) from more to less. According to the standard rate of strontium content in different types of groundwater and surface water analysis shows that the pore fissure water of Cretaceous and Neogene clastic rock is the highest (85. 4% on average), followed by Quaternary loose rock pore water, fracture fracture zone pore water, bedrock fissure water and carbonate rock fissure karst water (53. 2% on average), and the surface water is the lowest (32. 7% on average). Strontium is most easily enriched in pore fissure water of Neogene Cretaceous clastic rocks. The results of the study have an important guiding role in the exploration, development and utilization of mineral water resources in Gansu Province.
