摘要(Abstract)：
通过常规和地统计学分析,查明淮北平原浅层地下水中铁锰含量的空间差异性,得出变异函数图符合指数模型,二者都由结构性因素引起。对其空间分布特征进行分析表明,铁、锰在空间呈现相同的分布趋势,超标区主要分布在地势低洼地和低山丘陵区,其含量与岩土成分、地下水所处的氧化还原环境、地下水径流条件、酸碱性等有关。
Spatial variability of iron and manganese have been analysized by traditional and geostatistics methods.The results shows that both fit to the exponential model.In space,the distribution characteristics of both in the research are similar,and their contents are related to geotechnical components,runoff condition of groundwater and acidity-basicity.
