本文研究了吉林省西部9个县(市)、2665个病区10611眼潜井水含氟量,低氟潜水在高氟区存在与否及分布状况。结果表明,含氟量低于1.0mg/L以下的潜井占32.8％,有低氟潜水的病区占48.3％。证明近半数病区有低氟潜水水源。宏观与微观研究结果,高、低氟潜水在病区内镶嵌存在,与地理位置、河流多少等因素有关,且差异很大。病区低氟潜水分布无固定形态,与微地貌的变化、潜水经流和渗透、土质结构关系密切。土壤结构、成分、微量元素含量影响水的质量。高、低氟浅井周围混合土壤18种元素分析结果无明显规律性。
This paper studied the fluorine content of 10611 submerged wells in 2665 wards of 9 counties (cities) in western Jilin Province and the existence and distribution of low-fluorine submersibles in high-fluoride areas. The results showed that 32.8% of the total subsurface reservoirs contained less than 1.0mg / L of fluorine and 48.3% of those with low-fluoride subsurface water. Proof that nearly half of the ward have low fluoride diving water. Macroscopical and microscopic findings, high and low fluoride diving in the ward mosaic, and the geographical location, the number of rivers and other factors, and very different. The distribution of low-fluoride diving in the ward has no fixed form, which is closely related to the change of micro-topography, the flow and infiltration of submersible water and the soil structure. Soil structure, composition, trace element content affects water quality. The results of 18 elemental analysis of mixed soils around high and low-fluorine shallow wells showed no obvious regularity.
