| 摘 要： | 在分析对比国内外研究方法的基础上,选择数理统计方法,运用国际通用统计软件SPSS,对珠江三角洲地下水水质指标TDS、Cl-、SO24-、TFe环境背景值进行研究,并初步探讨了它们的空间分布规律及控制因素。分析认为地形地貌、区域水动力条件及海水入侵等因素对研究区浅层地下水指标的空间分布起主要控制作用。其结果为评价珠江三角洲地区地下水污染状况提供科学的依据。

| Abstract: | Based on a comparison of methods adopted both in China and abroad,the authors calculated natural background levels of TDS,Cl-,SO2-4 and TFe in shallow groundwater of the Zhujiang River Delta by using SPSS statistical software,and discussed the spatial distribution regularity as well as the controlling factors.The major controlling factors in the Zhujiang River Delta include mainly topography,regional hydrodynamic conditions and saltwater intrusion.The results obtained provide scientific references for the e... |
