地下水的资源功能与易遭污染脆弱性空间关系研究

The Spatial Relationship between the Function of Groundwater Resource and the Sensitivity to Pollution

本文以滹滏平原为研究区,从地下水资源功能和地下水易遭污染脆弱性内在联系为切入点,采用统计分析的方法,探讨地下水的资源功能与易遭污染脆弱性关系。结果表明,当地下水资源功能为一般时,地下水易遭污染脆弱性为一般或较低;地下水资源功能强或较弱时,地下水易遭污染脆弱性较高;地下水资源功能较强和弱时,地下水易遭污染脆弱性较低。当地下水易遭污染脆弱性一般时,地下水资源功能为一般或较强;地下水易遭污染脆弱性高或低时,地下水资源功能较弱;地下水易遭污染脆弱性较高或较低时,地下水资源功能强或较弱。然后从地下水补给和含水层状况等二者之间共有的评价指标分析了地下水资源功能较低和脆弱性低时形成多种对应关系的机理。

According to the intrinsic relation between the function of groundwater resource and its sensitivity to pollution, this paper deals with the spatial relationship based on statistical analysis with Hufu plain as the study area. The results show that, when the groundwater resource function is ordinary, strong or relatively weak, and relatively strong or weak, the groundwater sensitivity is ordinary or relatively low, relatively high, and relatively low, respectively. On the other hand, when the groundwater sensitivity is ordinary, relatively high or low, and relatively high or relatively low, the groundwater resource function is ordinary or relatively strong, weak, and strong or relatively weak, respectively. At last, the authors analyze the mechanism of various corresponding relationships based on the common evaluation indices.
