| 摘 要： | 通过对彭阳县74个饮用地下水进行取样分析,应用地质统计学的理论和方法,通过计算变异函数和克里金插值,分析研究了彭阳县饮用地下水中氟离子含量空间变异特征和空间分布特征,讨论了氟离子含量空间分布特征与地质环境的关系.结果表明:彭阳县存在引用地下水氟离子含量超标的现象,属于典型的高氟地下水区;地下水氟离子含量呈现明显的各向同性特征,在一定范围内具有很强的空间自相关性,且空间变异性是由大尺度的区域性因素引起的,而随机因素的影响不显著;空间分布上呈现出由南北向中间和由西向东减小的趋势;地下水中氟离子含量的差异是在各种地质环境因素共同作用下形成的,是地下水径流过程中各种因素综合影响的结果.

| Abstract: | Seventy-four drinking groundwater samples across the Pengyang County were analyzed using the theory and method of geostatistics.Through the calculation of variance function and Cringing interpolation,the spatial variability and spatial distribution characteristics of fluorion in drinking groundwater were researched and analyzed and the relationship of spatial distribution characteristics of fluorion with the geologic environment was discussed.The results showed that fluorion content about 32.43% has exceede... |
