摘要： 应用数理统计学及地质统计学方法,对安徽省淮北平原73个浅层地下水中氟离子、溶解性总固体数据进行分析。结果表明,氟离子、溶解性总固体均服从对数正态分布,变异系数分别为0.77、0.36。地下水氟离子、溶解性总固体半方差函数分别满足高斯模型、指数模型,氟离子在49.00 km内存在自相关,溶解性总固体在7.21 km内存在自相关。氟离子浓度>1 mg/L的区域分布在淮北平原东北部、中部。淮北平原溶解性总固体>1 g/L的地区主要分布在宿州和淮北,其空间分布特征与氟离子相似。

Abstract: Indexes of fluoride ions and total dissolved solids from 73 samples in shallow groundwater in Huaibei Plain, Anhui Province, ware measured. And the characteristics of spatial variation is analyzed by mathematical methods of statistics and geostatistics. Results show that: 1) Fluoride ions (F-) and total dissolved solids (TDS) obey the logarithmic normal distribution. The coefficients of variation were 0.77 and 0.36, respectively. 2) The fluoride ions and total dissolved solids from groundwater satisfy the Gaussian semi-variogram model and exponential model respectively. Fluoride ions have an autocorrelation in the 49.00 km. Total dissolved solids have an autocorrelation in the 7.21 km. 3) The zone with concentration of fluoride ions >1 mg/L is located in the northeast and central region of Huaibei Plain. The zone with concentration of total dissolved solids >1 g/L lies mainly in Suzhou and Huaibei cities in the Huaibei Plain. The spatial distribution characteristics of total dissolved solids are similar with those of fluoride ion.
